A compressed sparse column matrix, as used in Matlab and CSparse, etc.
In general, you should probably NOT use the class's constructors unless you know what you are doing. We don't validate the input data for performance reasons. So make sure you understand the https://en.wikipedia.org/wiki/Sparse_matrix#Compressed_sparse_column_.28CSC_or_CCS.29 correctly. Otherwise, please use the factory methods under CSCMatrix and CSCMatrix#Builder to construct CSC matrices.
