python - ip: Content update.

Log Message:
-----------
Content update.

Remove the Relation and Namespace section until a better idea of what they
should be is realized.

Add and change some mechanics to Query, Function, Portal, and Transaction.

Remove wording requiring that the Query attribute should be a type as it was an
unnecessary limitation.

Remove wording requiring that Connectors validate the capacity to make a
connection. An undesirable limitation that aided in resolving some questions
about the database, but ultimately was more of an impedance.
