Bionet - compile vecevent.mod on installation?

[tmchartrand]

The neuron VecStim definition, from vecevent.mod, is required to run a network with artificial cells created by bmtk - it would be great if it could be compiled and added to the path automatically, either on installation, or maybe when running build_env_bionet or something similar (ie. compile not only modfiles in the local network directory but also some core modfiles in a central directory).
