Classes/Levels

Have a way to add a class to someone, and have it (if that class has the feature) to add caster level to a previous class.

Basically some classes will add caster levels to like sorcerer, but isn't actual sorcerer level.
Hopefully this makes sense.. and I am fairly certain this will not be quick and easy resolution based on how classes files are currently setup.

Please ask if you have questions on this...

The problem is the classes that do this can be added at any time as a prestige class. and some of them don't start adding to caster level until their 2nd or so.
