GetCurvatures computes the curvature tensor and the principal curvatures at
%each vertex of a mesh given in a face vertex data structure
-FV -struct - Triangle mesh face vertex data structure (containing FV.face and
-toggleDerivatives - scalar 1 or 0 indicating whether or not to calculate curvature derivatives
-PrincipalCurvatures - 2XN matrix (where N is the number of vertices containing the principal curvatures k1 and k2 at each vertex
-PrincipalDir1 - NX3 matrix containing the direction of the k1 principal
-PrincipalDir2 - NX3 matrix containing the direction of the k2 principal curvature.
-FaceCMatrix - 4XM matrix (where M is the number of faces) containing the 4
%coefficients of the curvature tensr of each face
VertexCMatrix- 4XN matrix (where M is the number of faces) containing the 4 coefficients of the curvature tensor of each tensor.
-Cmagnitude - NX1 matrix containing the square sum of the curvature tensor coefficients at each vertex (invariant scalar indicating the change of curvature)
