find_graphviz on OS X

[GoogleCodeExporter]

Hi Ero,

Thanks for maintaining PyDot, it's very handy. PyDot has trouble finding
the graphviz executables on my machine (a Mac). The Mac version of GraphViz
tucks the executables into an application, so they don't usually make it
onto the path. They get put in

prefix/Graphviz.app/Contents/MacOS/ ,

where 'prefix' is usually but not necessarily '/Applications'. I don't know
if there's anything you can do about this, but thought you might like to know.

The manual solution would be to have the path to the binaries in the PATH 
enviroment
variable. pydot searches for the binaries in all directories listed there.

The path '/Applications/Graphviz.app/Contents/MacOS/' will be among the ones 
checked by default in the next 
version of pydot.
