Currently the extension API works, even though we are still lacking in 
functions. The extensions in SVN will not load by default unless you set 
the environment variable JOKOSHER_EXTENSION_DIRS to 
$mysvnroot/extensions/trunk and you have $mysvnroot/JonoEdit/trunk in 
your python path. Once the API is a little further to completion, this 
variable will be added to the startup script so that they load on default.

All of the descriptions from here: 
http://jokosher.python-hosting.com/wiki/ExtensionIdeas
need to be coded and then written up in here:
http://jokosher.python-hosting.com/wiki/TemporaryExtensionAPIDocumentation

Just remember when writing functions that the extensions should not have 
direct access to essential Jokosher objects. If you need to return a 
list of the available instrument (this one I already wrote), return a 
copy of Jokosher's list. If they need to get information from the 
pipeline, implement main_pipeline_get_property() instead of passing them 
the entire pipeline object (which could be dangerous).

And finally, please write more extensions! Here is the Hello World 
Jokosher extension:
#!/usr/bin/python
from Jokosher.Extensions import API
import gtk

#callback for menu entry
def HelloWorld():
	#launch gtk dialog
	dlg = gtk.MessageDialog(message_format="Hello World")
	dlg.run()
	dlg.destroy()

#called by Jokosher when it wants up to startup
def startup(API):
	API.add_menu_item("Hello World GTK", HelloWorld)

This extension will add a menu entry to the Extensions menu that when 
clicked will popup a gtk message box saying "Hello World".
