 * SUMMARY:  Scripts are loaded and resolved here.  They can potentially be of any language supported by the vm.
 * We're starting with dynamically loaded Java files, with support for Jython planned in the future.
 * The scripts must have a name unique per project, regardless of language they're written in.
