-  This file contains a class TriangleIndexVertexArray. I tried using the class with the same name
-  from the BulletX implementation and found it unusable for the purpose of using triangle meshes
-  within BulletX as the implementation was painfully incomplete.
-  The attempt to derive from the original class failed as viable members were hidden.
-  Fiddling around with BulletX itself was not my intention.
-  So I copied the class to the BulletX-plugin and modified it.
-  If you want to fiddle around with it it's up to you to move all this to BulletX.
-  If someone someday implements the missing functionality in BulletX, feel free to remove this class.
-  It's just an ugly hack.
