Placed the 'mode' variable into the class instance namespace.

Changed the processor type print out in the intro string.

Comment fix.

Converted the profile_flag variable to a bool.

Profiling is currently broken!

Added a docstring to print_stats().

Added some clarifying comments.

Bug fix for the get_intro_string() method, intro_string is no longer a class variable.

Big clean up of the relax module.

This was quite messy, and should be good enough for merging once all the FIXMEs are eliminated.

Spelling fix for a function name.

Sorted all class methods alphabetically.

This will really help with code navigation and debugging.
