.sync( schema )
Creates tables based on the the defined schema if they do not exist. If a table does exist, the actual columns in the database will be added or dropped based on the schema definition

Currently the sync function creates tables that do not exist. If the table does exist it will first drop any columns that do not exist in the schema definition and add any that do not exist in the current table. In the future, the sync method will also update the column's type and attributes. Re-ordering columns is not currently on the road map since not all database platforms have a clean method.
