The UserChoice processor allows the user to select from one of two choices. This is a sample processor, to show how sub-actions are called in a processor. Also, it demonstrates how a processor can choose to return data inside the tbwiki page dressing, or as it's own complete web page.

Call the macro with 2 lines of content, like so:

{{{#!UserChoice
apple
plum
}} }

In this example, if the user chooses apple, it will be shown in tbwiki context, but if they choose plum, the result will be on its own page.
