This commit switches the region set tag matching algorithm to using
unique prefixes. This enables the parser to recognise that the
summary vector
ROPR_UNI
should match up with the user defined region set 'FIPUNIT'. In the
current master sources, the above summary vector would produce a
diagnostic message saying that the region set 'FIPUNI' (without the
final 'T') does not exist.
We add a prefix-to-canonical region set name translation table to
the FieldProps class and funnel all FIP-like requests through this
translation table. In the case of non-unique prefixes-e.g., FIPUNIT
and FIPUNIX, we currently elect to have the last keyword entered in
the simulation model "win". This behaviour may be altered in the
future if deemed appropriate/necessary.
