barfowl 891772f58b Refactor public patch evalations methods exposed by Far::PatchTables:
- changes completely deprecate AddWithWeight(T, float, float, float)
    - added new EvaluateBasis() method to PatchTables
    - replaced usage of old Evaluate...<T,U>() methods with EvaluateBasis()
    - removed old Evaluate...<T,U>() methods
    - removed now unused Interpolate...<T,U>() functions in far/interpolate.h
    - moved low-level basis code from far/interpolate.* to patchBasis.*
