matplotlib Code

reorganizes py code

Modified setup to build array-package-specific extensions for those
extensions which are array-aware. Setup builds extensions automatically
for either Numeric, numarray, or both, depending on what you have installed.
Python proxy modules for the array-aware extensions import the version
optimized for numarray or Numeric as determined by numerix.
