Update post script regex to be more generic and remove duplicate require statements in generated code.
Merge branch 'master' of github.com:uiuc-cs428/uml2ruby into multi_parameter
Sort all operation parameters alphabetically for class diagrams
Call operation methods being printed as expected.  Added two unit test to check that object method parameters are being printed alphabetically when defined and when called.
Reverting changes not specific to removing duplicate require relatives and parameter ordering.
Add duplicate require check for activity diagrams.  Correct duplicate require check for class diagram.
Remove one line typo.
Get aligned with trunk.  Had some difficulty with Git making sure that only specific changes are in this branch.  The work flow is now getting more clear.
Ensure that calls to other activities also have sorted parameters.  Clean up how parameter comments are being printed.
Update a failing unit test based on white space error to use regex instead.
