Issue 206 : Example program cleanup

Item 4) Reorganized directory structure to make the examples a single project rather than a collection of independent apps.

    . All example programs moved under src/classes, and all are now in a subpackage of org.jdesktop.j3d.examples.

    . All resource files (geometry, images, audio) moved under src/resources

    . ant script now exists only at top level

    . Created netbeans project file for NetBeans IDE

-Write Once, Run Anywhere
-
-Platform independence is the cornerstone of the Java (TM) platform.
-This vision now extends to external input devices as well.  The
-overarching goal of the Java 3D input device architecture is to enable
-Java programs that use devices to run in a platform independent
-manner.  
-
-We encourage developers to use Java APIs for their drivers.  APIs such
-as the javax.comm API allow platform independent access to serial and
-parallel ports.  However, even if a driver is partially written with
-native code, the Java 3D InputDevice interface is layered on top of the
-driver such that once the native portion of the driver has been
-installed into the local JRE, the application code is platform
-independent.  
-
-In a future release, the Java 3D team is going to release a registry
-mechanism that will reside in the JRE as part of the Java 3D
-installation and allow registration of device drivers.  The
-SimpleUniverse utility will be modified to allow querying of devices by
-generic characteristics, and will subsequently look up and instantiate
-the appropriate device driver registered with the registry mechanism.
-The Java 3D team also expects to release a set of generic mappings for
-devices.  This will enable applications to count on the same behavior
-from different drivers for similar types of devices.  There will also
-be personalized profiles that enable a user to specify device mappings
-for features like dominant hand preference and eye position.  
-
-
-Overview of the InputDevice and Sensor APIs
-
-Java 3D abstracts the concept of a device via the InputDevice
-interface.  The developer's implementation of the InputDevice interface
-is layered on top of the device driver.  The device may be a real
-device such as a joystick or it may be a virtual device such as a piece
-of Java code that does transform calculations.
-
-A device sends data back to Java 3D by placing values into Sensor
-objects which the device code manages and updates.  The Sensor class
-encapsulates a transform and a timestamp.  The transform is specified
-in the TrackerBase coordinate system.
-
-Java 3D schedules calls to the device's pollAndProcessInput routine,
-which is a method in the InputDevice interface.  This method is
-responsible for updating the devices sensor values.  The sensors'
-values and time stamps are read by a user's behavior code and/or each
-frame (by the Java 3D implementation) when head tracking is enabled.
-There are several options for scheduling, and they are detailed in the
-InputDevice javadoc and in the section below entitled "Driver
-Scheduling and Blocking Semantics."
-
-Please read the javadocs for InputDevice and Sensor for more detailed
-information.  There is also a sample program in the Java 3D release
-called VirtualInputDevice, which implements these concepts in Java code.
-
-
-Recipe for an Application Program that Uses Input Devices
-
-Please see the Java 3D example program in the examples directory called
-VirtualInputDevice for an example of using this code recipe:
-  1) Implement the InputDevice interface with a class of your own
-  2) Call the device's constructor from your main program
-  3) Call initialize() on the device
-  4) Call PhysicalEnvironment.addInputDevice(InputDevice) or if you are
-     using SimpleUniverse, call SimpleUniverse.getViewer().
-     getPhysicalEnvironment().addInputDevice(InputDevice)
-  5) Assuming you want to modify the viewer's transform with the device:
-     add a WakeupOnElapsedFrames behavior to your scene graph that wakes
-     up every frame and in the processStimulus method modify the view 
-     transform with the transform you pull out of Sensor.getRead.
-    
-In a future release, it will be possible to replace steps 2, 3, & 4 with
-a single method call to the SimpleUniverse utility. 
-     
-
-Location for Installation of Device Drivers
-
-There are two suggested ways to package and distribute drivers.
-
-If a driver is written entirely in Java and if it is tightly coupled
-with a particular application without the expectation of reuse in other
-applications, then it should be bundled and distributed with the
-application itself.
-
-If a driver is not associated with any particular application program,
-if it contains any native code, or if it is expected to be used by more
-than one application program, then it should be installed directly into
-the end user's local JRE.  It is expected that most drivers for real
-devices fall into this category.  On the Solaris platform, the Java
-portion of the driver should be installed into jre/lib/ext as a
-uniquely named jar file and if there is native code it should be
-compiled into a shared object and installed into jre/lib/sparc.  On the
-Win32 platform, the Java portion of the driver should be installed into
-jre\lib\ext as a uniquely named jar file and if there is native code it
-should be compiled into a standard dynamically linked library (dll) and
-installed into jre\bin.  
-
-
-Using a Preexistent Native Driver
-
-It is possible to make a Java 3D driver out of a preexistent native
-driver.  In order to do this, you need to create an InputDevice
-interface that uses JNI to access the associated native driver methods
-whenever the corresponding InputDevice interface method is called from
-Java 3D.  The native portion of the driver must be installed into the
-target JRE.
-
-
-Package Naming Conventions
-
-All device drivers that are installed into the JRE should be part of a
-package that follows both standard Java and Java 3D naming
-conventions.  For instance, an input device driver should be placed
-into a package called
-com.<company_name>.j3d.drivers.input.<device_name>.  The package should
-be jarred up into a jar file that has a unique name.
-
-Any native .so or .dll files installed into the JRE should be uniquely
-named.
-
-
-Device Driver Constructor
-
-The constructor arguments for a device driver must be an array of
-strings.  So a driver should have a single public constructor that
-takes an array of strings.  The idea behind this requirement is that
-eventually the Java 3D registry will contain an array of string
-arguments to be sent to the device constructor at instantiation time.
-The SimpleUniverse API will also make a provision for optional String
-arguments to be added to the array of String arguments found in the
-registry.
-
-
-Driver Scheduling and Blocking Semantics
-
-When a device is registered with Java 3D via the
-PhysicalEnvironment.addInputDevice(InputDevice) method call,
-InputDevice.getProcessingMode() is called on the registered device.
-This method should return one of the three processing modes defined in
-the InputDevice interface:  BLOCKING, NON_BLOCKING, and DEMAND_DRIVEN.
-
-  BLOCKING signifies that the driver for a device is a blocking driver
-  and that it should be scheduled for regular reads by Java 3D. A
-  blocking driver is defined as a driver that can cause the thread
-  accessing the driver (the Java 3D implementation thread calling the
-  pollAndProcessInput method) to block while the data is being accessed
-  from the driver.
-
-  NON_BLOCKING signifies that the driver for a device is a non-blocking
-  driver and that it should be scheduled for regular reads by Java 3D.
-  A non-blocking driver is defined as a driver that does not cause the
-  calling thread to block while data is being retrieved from the
-  driver.  If no data is available from the device, pollAndProcessInput
-  should return without updating the sensor read value.
-
-  DEMAND_DRIVEN signifies that the Java 3D implementation should not
-  schedule regular reads on the sensors of this device; the Java 3D
-  implementation will only call pollAndProcessInput when one of the
-  device's sensors' getRead methods is called. A DEMAND_DRIVEN driver
-  must always provide the current value of the sensor on demand
-  whenever pollAndProcessInput is called. This means that DEMAND_DRIVEN
-  drivers are non-blocking by definition.
-
-It is important that you correctly classify your driver.  If it is a
-NON_BLOCKING driver, most Java 3D implementations will choose to add
-inertia inside the scheduling thread to avoid starvation of the other
-Java 3D threads.  If it is a BLOCKING driver, most Java 3D
-implementations will choose to spawn a separate scheduling thread for
-each BLOCKING device.  If your driver is a DEMAND_DRIVEN driver, your
-driver must always provide the current value upon request along with
-the current time stamp.
-
-When running drivers with the Solaris operating system using the
-Solaris reference 1.2 JRE and green threads, you should be aware that
-there is a bug that forces all drivers to be BLOCKING.  Thus, you
-should be careful to always use native threads on the Solaris reference
-1.2 JRE in order to get the expected behavior.  This is not an issue
-with the Solaris 1.2 Performance JRE release, which is native threads
-only.
