Collapse definition and schema files

[gracebrownecodes]

I think the split between "definition" and "schema" is more trouble than it is useful. IIRC, we originally split them so that folks who are only interested in the definition-type attributes like description don't have to see the schema-type attributes like field type, length, etc. So far, I don't think we've found any users like that. In fact, most of the users are interested in seeing all the information together and would rather not have to refer to two files in order to see it all.
