#32 Allow users to filter out arbitrary columns from templates

[Dave Neuer]

add a filterColumns table to TableDecorator.java so
users can filter out columns (i.e. from the results of
mandatoryColumns & allColumns -- which, for whatever
reason --- like being defined in a base Entity class
-- they don't feel belong there).

That should have read "adds a filterColumns 'METHOD'"
