Things To Do

 add module library, submodule of model.
+
+  In the library module, there should be a LibraryLoader class and a LibraryIF.  The LibraryLoader will have a method loadLibrary(String name) that returns a LibraryIF.  The loader should contain information about each of the implemented libraries.  The loadLibrary() method will check for a library with the matching name, return it if available, or throw an exception.
+
+  LibraryIF should have methods getConstants() and getFunctions() that return the constants and (regular, not system-level) functions associated with those libraries.  ModelIF should contain a method addLibrary(String name) that calls loadLibrary(), then uses getConstants() and getFunctions() to add the library's constants and functions to the model.
+
 also add system level function definition in semantics, next to Executor.
+  
+  LibraryIF should also have a method getSystemFunctions() that returns the IDs of system-level functions in the library.  These IDs would then be used by the executor to execute the system-level function.  Maybe have a lib folder in the semantics package as well, with a library semantic interface for the executor to pass an environment and function ID to the appropriate library?  This would be like having an executor for each library that contains system-level functions, and the current executor would call the appropriate library executor.
