/**
* @module Tools
*/

/**
* BaseTool provides essential functionality for Tools including handling of the activate toggle, setting `busy` state, injecting output float into the page,
* and templating the output. It's not required to mixin BaseTool, but it's really helpful; and of course any of the BaseTool methods/properties can be overwritten
* after mixining it in.
*
* Call `initToggle` to initialize the tool.
