/**
 * MayaGroup - A MayaGroup is equivalent to a Maya Transform Node
 * 
 * If you are post-multiplying matrices, To transform a point p from object-space to world-space you would need to
 * post-multiply by the worldMatrix. (p' = p * wm) matrix = [SP-1][S][SH][SP][ST][RP-1][RA][R][RP][RT][T] where R =
 * [RX][RY][RZ]  (Note: order is determined by rotateOrder)
 * 
 * If you are pre-multiplying matrices, to transform a point p from object-space to world-space you would need to
 * pre-multiply by the worldMatrix. (p' = wm * p) matrix = [T][RT][RP][R][RA][RP-1][ST][SP][SH][S][SP-1] where R =
 * [RZ][RY][RX]  (Note: order is determined by rotateOrder) Of these sub-matrices we can set [RT], [RA], [ST], and [SH]
 * to identity, so matrix = [T][RP][R][RP-1][SP][S][SP-1] matrix = [T][RP][RZ][RY][RX][RP-1][SP][S][SP-1]
