This is a sample action controller illustrating how to create
additional ''operations''.
Add the `vote` operation to a workflow action, for example:
{{{#!ini
vote = new -> new
vote.operations = vote

Don't forget to add `VoteOperation` to the `workflow` option
in the `[ticket]` section of TracIni. When added to the default
value of `workflow`, the line will look like this:
{{{#!ini
workflow = ConfigurableTicketWorkflow,VoteOperation
