Detailed Description

Fermion operator with CRS matrix format.

This fermion operator class is defined by CRS matrix format which is widely used in studies of linear algorithms. The matrix is defined by giving fermion operator, or reading from a file (filename is provided at construction). In present implementation, this class works only on single node. Parallel version should be implemented. [07 Dec 2011 H.Matsufuru]
