Fixes for test_create_pseudo_spin() and test_create_pseudo_spin2().

The pseudo-spin name and number is now stored in the member spin containers.

This gives a mapping between from the spin to the pseudo-spin.

Modified the checks for the pseudo-spin creation unit tests.

Wrote a second unit test for the creation of a pseudo-spin.

Added some more checks for the test_create_pseudo_spin() unit test.

Changed the default value for 'int_cpmg' to avoid an impossible mathematical situation: ln(0).

A few fixes based on the unit tests problems.

Added more unit tests and tried to debug what was uncovered by these tests.

Still more work is needed for debugging...

Removed the dependence of the relax_errors and relax_warnings modules on relax.

This fixes some rare circular import failures with the --debug flag and makes the modules much
cleaner and more independent.

Improvements to the relax_errors module.

The module function save_state() can now function if this module is used by something other than
relax. The saved state is also BZip compressed if the bz2 module exists.
