CPPLapack Code

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.

The data storage for dgsmatrix and dssmatrix was modified.

the type of Line and line object of dssmatrix were changed to std::vector.

*change some CPPL_DEBUG lines to CPPL_VERBOSE lines.

*halfway development of dssmatrix

dssmatrix was renamed to dgsmatrix.
(zgsmatrix is under construction.)

modification to get rid of forbidden codes
*added nullify function for all smart-temporary classes
*put nullify() at the end of shallow_copy functions and shallow copy constructors
*modified destroy function to assign NULL to all pointers

Row and Col were added in dssmatrix for faster search of (i,j) component

The trunk cpplapack source code was added.
