Significant changes to work with the new account/ledger structure. Removed much of the auto-generated model association code. Added helper functions into the models to perform model related work, such as model 'stats' (a bad name for a function to return a summary of pertinent financial information from a given model instance). There is a ton of cleanup to do, but first I want to get it all captured.
