Tests for the ScaLAPACK Band and Tridiagonal LU routines

The LU test program generates random nonsymmetric band test matrices with values in the interval [-1,1], calls the ScaLAPACK routines to factor and solve the system, and computes a solve and/or factorization residual error check to verify that each operation has performed correctly.

Specifically, each test matrix is subjected to the following test:
