              As a follow-on ticket to 4605, this means adding the support for altering a table more easily. Specifically, this means doing something like:

              alter("table").addCoprocessor(…)
alter("table").addColumnFamily(…)
…

              and then for constraints, something like:

              alter("table").addConstraint(…)
alter("table").enableConstraints
…

              with those methods being added dynamically by a 'constraint module' in the jruby code. This would also serve as an example for how further shell extension can be done in a modular manner.

              This ticket may also become a more major revamp for the how the shell works, e.g. dropping into a table context, etc as described in the discussion.

              Linking to jira for getting an individual table. The original pain around this was in that constraints only make sense for a single table, so we could just dynamically tie it to a table.

              By dynamically, I was thinking either via opening the Table class back up to add methods or doing a dynamic lookup of all classes in a table-extensions folder and including them in the Table class.
