CPPLapack Code

minor modifications to suppress warnings about implicit casts

A lot of minor changes has been done.
Probably there are no need to modify your project codes using CPPLapack.

Main modifications are the followings.
1)All the private menmer objects (e.g. M, N, Array, etc.) were removed and put in public.
This modification made CPPLapack unsafe a bit and extendable a lot.
We highly recomend CPPLapack users to use valgrind with building your codes in debug mode.
2)Some implicit cast operators were removed.
Use to_XXXmatrix() functions instead.

name of member objects in dgsmatrix was modified.

specs of dgsmatrix and dssmatrix were changed a little.
They save uint32_t data for matrix index data instead of long integer.

The data storage for dgsmatrix and dssmatrix was modified.

*dgsmatrix::operator<< was modified.

*fix write functions again.

*bug fix for write functions.
*remove CPPL::min and CPPL::max functions, and replace them to std::min or std::max.

*std::ofstream CPPL::ofs was added to control output format of write fnctions.

*row and col functions were added for all d*matrix classes.
