updating model files query engine interaction
added simulation initialization functionality to the model class
switched file handling to the xml file loader
quick fixes to app
updated models to now enter the simulation after being loaded
updated the file loader to only load modules. catalog support has been taken out for now. the input xml class has been fully replaced by the xml file loader class. fixes #358.
removed notion of prehistory. that's now taken care of by our init process
updated error class in the xml engine
updated xml engine documenatation and removed empty constructor
some work done on testing the xml engine/loading. it's not working as I expected, so I'll have to review, perhaps retool.
