Tests for the ScaLAPACK Band and Tridiagonal LLT routines

The Cholesky test program generates random symmetric positive definite band or tridiagonal test matrices with values in the interval [-1,1]. It then calls the ScaLAPACK routines to factor and solve the system, and computes a solve residual error check to verify that each operation has performed correctly.

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