Merged PetitTeton webapp with the inventory tracking app; Moved the database configuration out of git and added an example configuration; Added migrations to the mix so that we can easily update the production database and roll back changes to the database (from the command line install migrations [may not be necessary?]:

npm install -g sequelize-cli

To update the database after updating the app from git (on the command line in the webapp base directory):
sequelize db:migrate

To undo the last migrations:
sequelize db:migrate:undo
