Detailed Description
A ProfileSPDLinDirectThreadSolver object can be constructed to solve a ProfileSPDLinSOE object. It does this in parallel using threads by direct means, using the 
variation of the cholesky factorization. The matrx 
is factored one row block at a time using a left-looking approach. Within a row block the factorization is performed by 
threads. No BLAS or LAPACK routines are called for the factorization or subsequent substitution. \
