[WIP][nocompile] begining of DenseMatrixem and Dense Dense MMul. Likely
ending branch here
commit 808660d19dcba0b1d1bd8e6f13ed466821fc0196

[WIP][nocompile] out of time tonight. Need to consider wheather JCUDA
needs to repacked mahout in-core matrices (row-major) as column major per the
wrapped call to NVIDIA cublasDgemm operation. The fact that cusparse uses CSR
rather than CSC is somewhat confusing in this case (for e.g. a Dense %*% Sparse

WIP: Dense
commit aa8fdcfa0260e86f8702048d6b5b9777ccbf5aa2
Author: Andrew Palumbo <[email protected]>

[WIP]: late. 2 compilation errors Dense is somewhat solid. Sparse may need
to use transposes. need to check values in unit tests, and transpose in dgemm
call as needed
