psVectorFitPolynomial1DOrd ignores polynomial element mask

[eugene]

the fitting process is supposed to exclude elements which are masked from the
fit. it does not do this. In the matrix A, the rows and columns corresponding
to these elements should be set to 0, while the diagonal elements corresponding
to these elements should be set to 1, as should the corresponding elements of
the B vector. an example can be seen in the p_psMinLM_SetABX

[eugene]

it looks like this has been included in the current release (10)

i take it back; this was *not* included in the current release. I have fixed it
in the ifa psLib branch. I will attached the reference.

The polynomial fitting functions now respect the term mask.
