Title: hepmc: 2.06.09 - High energy physics tool (C++ event record)

This is probably most appropriate for the science tap.

Their CMake setup stops the build if the binary tree is within the source tree, so I have needed to go up a level when creating the build directory. Please let me know if there is a better way to achieve this.
