\&\fIfill_cache()\fR loads the entire Enum into memory.  This should only be called
for index Enums \*(-- never for primary Enums.

.PP
Reset the Enum to the top, so that after \fInext()\fR is called, the Enum is located
at the first term in the segment.
.PP
\&\fInext()\fR advances the state of the Enum one term.  If the current position of
the Enum is valid, it returns 1; when the Enum is exhausted, it returns 0.
.PP
For an Enum which has been loaded into memory, scan to the target as quickly
as possible.
.PP
Setters and getters for members in the SegTermEnum struct. Not all of these 
are useful.
