crng 1.1: Random-number generators (RNGs) implemented as Python
extension types coded in C.

This is a minor upgrade from version 1.0.

The most important changes in version 1.1:

- The script (or module) 'crng_pickle.py' has been added, which
  performs setup for using the crng module with the pickle/cPickle
- A new utility function 'stir' has been added; it shuffles a list 
- The types Ranlux and MT19937 now have an initialization argument
  'state' and the corresponding attribute, which allows save/retrieve 
- The 'repr' function has been properly implemented for all RNG types. 
- A script 'setup.py' has been contributed for installation using the
  Distutils tools.

The Python module crng implements random-number generators (RNGs)
based on several different algorithms producing uniform deviates in
the open interval (0,1), i.e. exclusive of the end-point values 0 and
1. A few continuous and integer-valued non-uniform deviates are also
available. Each RNG algorithm is implemented as a separate Python
extension type. The RNG types are independent of each other, but have
very similar interfaces. The entire module is implemented as one
single C source code file.
