Documentation Update of SchoolType

It is brought to our attention by ScottKuykendall that the documentation of SchoolType is published identical with SchoolCategory in the Education Organization Domain Descriptor Tech Doc. That needs to be corrected by replacing the documentation for the SchoolType with the following definition:

The type of education institution as classified by its primary focus such as Alternative, Career and Technical Education, Regular, or Special Education schools.

Based on this update on the SchoolType in the Tech Doc, review the the Usage Classification for the SchoolCategory in the same chart and make any correction needed.

In addition to the Tech Doc correction, I also recommend updating the descriptor in the model since the documentation in the model is also not clear enough even though it is different from what is shown in the Tech Doc.
