Reorganize math code into: com.jogamp.opengl.math and com.jogamp.opengl.math.geom packages
Note: WIP - We may relocate / reorg math package. Public relocations: com.jogamp.opengl.util -> com.jogamp.opengl.math - FixedPoint - FloatUtil com.jogamp.graph.math -> com.jogamp.opengl.math - Quaternion - VectorUtil com.jogamp.graph.geom -> com.jogamp.opengl.math.geom - AABBox VectorUtil: Introducing Vert2fImmutable and Vert3fImmutable interfaces, allowing graph Vertex instances to be used 'graph' agnostic and to document 2d/3d use-cases.
