Contributors & thanks added to readme
Clarifying documentation around using the view helpers and fixing some mistakes.
Split out method naming logic.
Fix to signature of method namer
Splitting the large ButtonSet#initialize method into smaller methods.
Narrowing signature of methodnamer
Extracting MethodNamer to its own file. Updates to ButtonSet tests to get it working and to require less setup. I'm less pleased with these tests since the now veer from the readme.
Readme states that button helper takes symbols and strings, so I've added a test and code to support that.
Slightly less bad approach to handling all button set name formatting in one place. Still seems awkward, but better.

Fix attempt for an integration project
Revert "Fix attempt for an integration project"

This reverts commit 2a223655705526140f9a51215ece8dabe5fc2860.
Documenting and implementing the :autosave => :true setting for the hstore_radio_data association
Naming improvement. ButtonOptions becomes ButtonDefinition. Moving towards it being a configuration definition that is used by ButtonSet, which will become more factory-like.
Button definition is now configured after instantiation and not during. More explicit what is going on.
Removing the duplicated call to ButtonSet.new. Might as well wrap that interface call up in a method.
