Appcelerator Titanium Module

Create a Appcelerator Titanium Module that extends their implementation of Google MapView and allow for views to be added to MapView Annotations. Currently, Appcelerator's Titanium only allows static images to be added to the Annotations. I require a custom view or custom button to be added. In addition, the module should be optimized for allowing up to 400 or so custom buttons to be added to the MapView without crashing the application.
