This commit contains various changes
1. Compressed Sparse matrix multiplication
2. modified matrix multiplication to push down information of
transposing to the ba+* op. to allow not decompressing the matrix.
3. Configuration option of enabling and disabling overlapping compression
4. decompress row section direct access to the matrix block not using
quick set/get.
5. adding safe boolean to decompress to specify if management of
nnz should be done.
6. Col Group Partitioner Cost, now estimates all joins to not include 20%.
7. Add configuration for sampling ratio
8. DML Config settings for Cocode-Compression method
9. Lowered default sampling size to 0.01
10 . add support for right sparse matrix multiplication with overlapping
