castxml 0.1+git20160202 (new formula)

CastXML is the successor of GCC-XML.

CastXML is a tool based on LLVM/Clang that generates the same XML output format as GCC-XML.
It is used by multiple projects like pygccxml and ITK (and all projects using py++ to build python bindings)

The version number follows the one from the debian package (https://packages.debian.org/sid/castxml)

Closes Homebrew#49096.
