''' Statusbarmenu
A menu that lives in the status bar
A set of tools to add or delete custom buttons from the toolbar. This may not be super robust, but seems to work ok. Button objects and actions are saved so they survive global clearing, but thid has not been tested extensively. If a function relies on imports that occured outside of the function, these might dissappear -- user must make sure those modules are added to a module that is kept by pythonista, such as anything in site-packages, or name starting with __ '''
