Adding default filters

To allow focusing on the most common cases, creators can define default filters for concepts in Veezoo. For instance, consider yourself planning a new ad compaign. Typically, you are only interested in customers who have opted into the mailing list. When an according default filter is set, answers to questions about customers will by default be restricted to customers who have opted in, unless you explicitly ask for opted out customers. This eliminates the need to specify this criterion in every query.
