Description

Currently, the compression framework does not allow one to compress a MatrixBlock containing NaN values.
While the allocated compression block does not support operations on matrices containing NaN it does not mean we cannot compress it still.
This task is to compress a MatrixBlock containing NaN values, and in the process of compressing replacing all NaN values with 0 and Write a warning in case a Nan is discovered.
