Initial setup of infrastructure.
Created a maven project based on Spring Data JPA. Created JdbcRepositoryFactory, which actually creates Repositories. Wired the construction of meta data. Implemented a dummy version of saving an entity to demonstrate availability of meta data. Included a simple test for exercising the JdbcRepositoryFactory and the resulting JdbcRepository. Related pull request: #5.
