Removed commented out code. Finalized cross-device assignment (Not ideal for CPU, but enough for benchmarking GPU).

Added basic functionality for cross-device copy assignment. Removed StripSize template typename as it was never used anywhere.

Fixed setCompressedRowLengths by getting around const vector. Fixed getStripLength and getGroupLength by using accessing methods instead of []. Fixed addElement to multiply the present value rather than the value that is being added.

Implemented fix for case when roundToMultiple would give a number smaller than the number of rows, thus causing index to be out of bounds on CUDA. Debugging prints included
