Some changes to the Vec class and VecTraits in anticipation of creating Vec-like objects. The following changes are made: * Add GetNumberOfComponents to Vec, which returns NUM_COMPONENTS. * Likewise, all VecTraits have a GetNumberOfComponents method. * The ToVec method in VecTraits is changed to CopyInto so that it can be used when the length of the Vec-like is not known. CopyInto is also added to Vec. * VecTraits has a typedef named IsSizeStatic which is set to VecTraitsTagSizeStatic when the number of components is known at compile time and VecTraitsTagSizeVariable when the number of components is not known until runtime.
