public class SQLMap
extends SQLProxy
implements Map<String,Object>

This class implements a map that mirrors its contents into a SQL database - The map represents the root map that is linked into the SQL database as one table - Subsequent maps map to subsequent SQL tables A SQL table has the following structure: - name:text | type:integer | value:text
