better use of templates for Cholesky factorization * liboctave/numeric/chol.h, liboctave/numeric/chol.cc: New files generated from CmplxCHOL.cc, fCmplxCHOL.cc, floatCHOL.cc, CmplxCHOL.h, dbleCHOL.cc, dbleCHOL.h, fCmplxCHOL.h, and floatCHOL.h and converted to templates. * liboctave/numeric/module.mk: Update. * __qp__.cc, chol.cc, CMatrix.cc, CMatrix.h, dMatrix.cc, dMatrix.h, fCMatrix.cc, fCMatrix.h, fMatrix.cc, fMatrix.h, eigs-base.cc, mx-defs.h, mx-ext.h: Use new classes.
