Removed the nesting of the RelaxWarnings and added the global variables Debug, Pedantic, and relax.

Fixed a few small bugs so that the relax prompt interface would at least start up.

The Debug flag and Relax instance are placed as globals in the 'errors' and 'warnings' modules.

Removed the Debug and Pedantic flags from __builtin__.

This was suggested in the thread starting at
https://mail.gna.org/public/relax-devel/2007-02/msg00003.html (Message-id:
<45DACFEA.7020108@...>).

The flags have been shifted, possibly temporarily, into 'self.relax'.

Removed the 'warn' flag as no parts of the program appear to be using it.

Added the relax and Debug global varibles to the error module.
