Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args, &block) ⇒ Object

Ensure args and block are both empty. Creates a Mao::Query for the name invoked, which ensures such a table exists. Assuming it exists, a Mao::Filter::Table for that query is constructed.
