The Jython Controls allow for the development of custom layer controls written in Jython. The controls operate in two modes.
First is the "developer" mode. Here the developer can create a Jython Control; specify the name of the display, any data categories, and the probe type; and write the Jython that creates a GUI and responds to data, animation time and probe position changes.
The default Jython code has examples of accessing data, etc.
The second mode is "user" mode. In developer mode you can write out an specification of the Jython Control to a plugin through the File->Save->Write to Plugin menu. This plugin, when loaded, will only show the user interface that is created by the developer-written Jython.
