Additional attributes

• part:
  start | meta_query | date_query | run

  It allows us to break complex queries into parts. part attribute is used when we use ‘users_builder‘ attribute. It gives us the ability to add or remove parts of a query based on conditions.

  When the part is start it destroys all existing parts and creates a new query, so it is important that when you are breaking a query into parts, part=start is first. Part meta_query indicates that JSON value is to be used for creating meta query and part date_query indicates date query it is applied to user_registered field.

  If the part is not used, then query executes immediately, else it only executes when it finds part=run.
