Hi,
In my different developped plugins (Kaamelot and others in-house plugin), the ability to implement a new scheme is very recurrent.

It would be more pratice to have a detailled "getting started documentation" on how to implement its own scheme in a plugin.
Currently, I am not sure that I will be able to do that without some improvments in existing classes.

I supposed that to resolve JRA-3821, new Schemes will be created. A step by step documentation would be very usefull.
