Log:
Addition of the relax status singleton object.

See https://mail.gna.org/public/relax-devel/2010-01/msg00094.html and other 
related posts in the
thread.

The idea is that various parts of relax deposit status information into here 
that other parts of
relax can then use.  For example the Monte Carlo code can place the current 
simulation number in
there while the relax GUI controller can read these values.
