Description:
    Stubs out a new dradis import plugin. Pass the plugin name, either CamelCased or
    under_scored, as an argument. The plugin name will be extended with '_import'
    if this is not part of the plugin name argument.

    This creates a plugin in vendor/plugins including an init.rb and README
    as well as standard lib, task, and test directories.

Note:
    The basic structure is exactly the same as a standard Rails plugin. With a the
    unneeded files and code removed and a bit of customisation to fit the dradis
    export pugin requirements.

Example:
    `./script/generate import_plugin Wiki`

    creates a standard import plugin:
        vendor/plugins/wiki_import/README
        vendor/plugins/wiki_import/init.rb
        vendor/plugins/wiki_import/install.rb
        vendor/plugins/wiki_import/lib/wiki_import.rb
        vendor/plugins/wiki_import/test/wiki_import_test.rb
        vendor/plugins/wiki_import/tasks/wiki_import_tasks.rake
