Goodbye fake storage, welcome JPA with appEngine. Notes:
1) Currently there are just 2 entities: Employee and Report. Any new entity must be added to the list in persistence.xml
2) Fixed findReportsByEmployee call.
3) A Report entity cannot  refer to an Employee entity -- it instead refers to
the Employee key due to current appEngine implementation

4) Running the project requires GPE because the appEngine jars are not present in our tools.
