CPPLapack Code

*Some warning messages are modified.

drovector_small::write was revised.

Some 'std::' missing before functions like atan2, cos, sin and sqrt were added.
Thank you, Florian!

hadamerd product functions were added. (incomplete)

Some CPPL_DEBUG traps were added for small matrices.

VERBOSE is substituted by CPPL_VERBOSE.

*The default file format of write and read function was changed.
The write functions append a '#' at the very begining of the file.
For the backward compatibility, read functions can read files without the '#'.

*The style of "[ERROR]" messages was slightly changed.
