Heterogeneous ScaLAPACK (HeteroScaLAPACK) 1.0.7-BETA

The sources are given meaningful names.

All the function calls to the HeteroMPI routines are isolated in the files ending with _hmpi_intf.c.
All the functions used in the performance models are placed in the files ending with _info.c.
All the information functions giving the number of computations and comunications are in the files ending with _info.c.
Each context routine is placed in a separate file ending with _ctxt.c.

The following ScaLAPACK routines are completely implemented and tested for this release.

1). PCGESV, PDGESV, PSGESV, PZGESV (General linear system of equations)
2). PCGELS, PDGELS, PSGELS, PZGELS (Least squares)
3). P*GETRF, P*POTRF, P*GEQRF, P*GELQF (LU, Cholesky, QR, LQ factorizations)
