Reorg multiple sections consolidate what you can/can't do to the schema into one section and move to the top of the Tracker Schema section.. Also outline how you *can* change the type of a property. In the "Classes and Properties - creating a new information store section", add new Method subsection after Properties subsection. Place all 4 method sections in there moving them from below. Move IssueClass section before FileClass section because IssueClass incorporates links to FileClass not the other way around. Fix indexes.
