STEP AP 242 Parser

STEP is the current standard for exchange of CAD data between different software packages. BRL-CAD makes use of the STEPcode project to implement its step-g importer, but it is currently hard-wired to the AP203 application protocol.

For this project, you'll get an AP242 parser working within our step-g importer. You'll heavily document everything you do, keep notes on and discuss any issues encountered, and try to import as much geometry as possible from an AP242 source data file.
