13	How-to build an application using guiframe:
14
15	1- Write a main application script along the lines of dummyapp.py
16	2- Write a config script along the lines of config.py, and name it local_config.py
17	3- Write your plug-ins and place them in a directory called "perspectives".
18	- Look at local_perspectives/plotting for an example of a plug-in.
19	- A plug-in should define a class called Plugin. See abstract class below.
