Least-Squares optimal affine subspace

Computes the affine subspace (eg, line, plane) that optimally fits the input data

The zip includes:
(1) lsqAffineSpace: a 'low level' routine that takes a set of m-dimensional real sample data and returns the optimal-fit k-dimensional affine subspace, with some options for discarding outliers.
(2) lsqPlane and lsqLine: lsqAffineSpace wrappers, that compute optimal line and hyperplane (plane, if the samples are 3-vectors) of the input samples.
(3) lsqAffineTestScript: demonstrating usage of the functions.
