Class herm_matrix_timestep_view serves for interfacing with class herm_matrix_timestep without copying the data.
Occasionally you may have a pre-defined object of herm_matrix or herm_matrix_timestep that you want to use. While one option is to make a copy of the data, most commonly you probably want to re-use this memory as a libcntr type, and this class serves as an interface. Mark similar concept of a map class in Eigen. To construct this class you need: a pointers to the region of memory defining different components (ret,tv,les,mat) and usual defining constants for the herm_matrix_timestep. The contour function can be of scalar type or matrix-valued.
Square-matrix-type contour functions are fully supported, while non-square- matrix contour functions are under development.!! NOTE: MIND DANGLING POINTERS
