4b0dd54f15 Add CUDA implementation of the DILU
preconditioner. Uses graph coloring to exploit
parallelism in upper and triangular solves when
computing a diagonal approximate inverse of a
sparse matrix. Supports blocksizes up to 3.

533c5a1a3e Combine new diagonalMV kernels into one using
template arguements.
Use more consistent naming conventions.
Change printing function of CuVector from output
stream overload to toDebugString().

1e4b0e97ee Add jacobi preconditioner that runs on the GPU.
Implement calls to cuBlas, cuSparse and implement necessary
CUDA kernels to perform a single iteration of the jacobi preconditioner.

Add tests that verify new kernels and the preconditioner in its totality.

The preconditioner is verified on 2x2 and 3x3 blocks, which as of now
are the only supported sizes. 1x1 are not supported because cuSparse
does not support it.
