Fixed bug in IsParallel method in Vector3D
Dot Product of 2 parallel vectors is only 1 iff the product of their
lengths is 1
Fixed bug in Vector3Ds IsParallel and IsParallelNear
Vectors in that calculation should be normalized since
the dot product of 2 parallel vectors is 1 iff the product of their
lengths is 1
Fixed the Max functions in the Vector classes
The copy and paste is strong with this one...
Removed parallelfix from branch for compatibility with master branch
