** annotationTable.h
**
** A global table that keeps information on the user-defined annotations.
**
** For each annotation, we need:
**
**    o [key] A name (matches @name@ in code)
**    o State - index into metaStateTable that identifies the state associated with this annotation
**    o Value 
**    o Context information (where can annotation be used)
