removed OrderStatus and ProjectStatus models, instead incorporated the status values as static values in UserProject and SampleSubmission models. This immediately allows the status to be available when loading up the app. I did not change the Phenotypetype class to a static status variable inside Phenotype class, since that would not allow users to add anymore possible Phenotypetypes into the database and that would be limiting. In terms of the project status and order status - I think these should be well-decided beforehand.
