[Matplotlib-users] Spooling up on matplotlib .... run all the examples

matplotlib is impressive in its capabilities, I didn't realize how much so
until I download from the git, and made a little script to run all of the
examples.

I'm way too much of a newbie here to check anything in, but I thought
someone may find this trinket useful.  As written, it should be in the
'matplotlib/examples' directory named 'runAll.py', if someone is so inclined
to check it in.  Feel free to edit or eviscerate it or whatever.

###To make the demos work that needed sample data I had to 
### 'cp /etc/matplotlibrc ~/.matplotlib/'  and edit the examples.directory 
###  entry to not have the extra tick marks ie
### """examples.directory : /usr/share/matplotlib/sampledata"""
### but I think this was because of a version issue....

            not fpth in excluded)
