Rathar than placing the 'C_module_exp_fn' variable into __builtin__ from the specific_fns.relax_fit
module, it is now placed into the global namespace of that module. The generic_fns.runs module then
simply imports the variable.

Removed the unneccessary usage of __builtin__.

The following varibles have been shifted from __builtin__ to the global namespace of the 'io' module
as only this module was accessing them:
bz2_module
bz2_module_message
devnull_import
devnull_import_message

added rudimentary command line and tests for direct paths to tests cases

Added the RelaxErrors to the interpreter module.

Imported all the RelaxErrors and RelaxWarnings, as well as warn(), into the structure module.

Fixed the RelaxErrors in the 'relax' base file.

Recreated the AllRelaxErrors object!

A small bug fix with the 'errors' import rather than 'relax_errors'.
