The Generalized Nonsymmetric Eigenvalue Drivers

The driver routines for the generalized nonsymmetric eigenvalue problem are
xGGES
generalized Schur form driver
xGGESX
expert version of xGGES (includes condition estimation)
xGGEV
generalized eigenvalue/eigenvector driver
xGGEVX
expert version of xGGEV (includes condition estimation)
For these driver routines, some tests are done by generating random matrix pairs of a dimension and type chosen by users, and computing error bounds similar to those used for the nonsymmetric generalized eigenvalue computational routines. For some tests, one can use a file of precomputed matrix pairs and condition numbers.

The parameters that can be varied in the random matrix pair tests are:

175#175
the order N of the test matrix pair 174#174
175#175
the type of the test matrix pair 174#174
