New term: Functional tooth

[GoogleCodeExporter]

We have, currently, 

tooth
restored tooth
functional prosthetic

I believe there should be a superclass of these three.

Not a great solution would be to assert an additional superclass. Perhaps we 
defined 'tooth function', say that each of these bears the function, and create 
'functional tooth' as a defined class - anything that has 'functional tooth' 
role.

Then we need to examine what we have asserted about each class and perhaps 
reassign the target:

Different nomenclatures for teeth should be attached to functional tooth, I 
think, as they are equally applicable to members of all three subclasses. 

Some disorders/finding, like fractured/broken tooth are applicable to all.
Some, like caries, are applicable to anything that has tooth as a part, i.e. 
natural and restored teeth
etc.

Added the class but not the function yet, nor replaced any uses of tooth with 
functional tooth. Still needs work.
