v2.0 Proposal: Internal reorganization and Schema creation support.

I am using this Gem but had to make many updates to meet my project needs and to also support Ruby 2.0

Internal reorganization and Schema creation support.
   - Refactor fixture yaml structure
      - Support seperate sections for the data vs. the schema definition of the database so that the tables may be created for proper in-memory DB testing
      - Data section is now an array to coincide more closely with the concept of a list of rows in a table
   - Add Table and Row classes to represent the Data sections of the fixture and to add SymbolMatrix-like support
   - Allow the fixture path to be configurable
   - Remove cucumber functionality since the industry is moving away from it
   - Use sqlite3 Sequel adapter to inject data into memory.
