C-Squared Histograms
Aaron Gindi

This library is designed to facilitate user control over the trade-off between precision and memory usage of histograms,
which are often essential in memory research.

Instead of implementing memory saving operations, this library merely simulates the operations for evaluation purposes.

Patch 0.2.0: Fix bugs relating to CompressedHistogram and made CompressedHistogram more efficient. Breaking change
because Copy trait was removed from Param implementors, and C2Params now return references to embedded parameters
instead of copies.
