phpCallGraph

While PHPCallGraph was initially developed for object-oriented code, this release adds the ability to analyze user-defined functions.

Also code in the global scope (outside any functions or methods) can now be analyzed with the help of a little workaround: Such code can be manually wrapped in a dummy function called dummyFunctionForFile_filename_php() which will then be recognized by PHPCallGraph.

Of course this is not very elegant but currently the only feasible way due to some conceptual restrictions resulting from the utilization of the InstantSVC CodeAnalyzer.
