Unicode version of Charles C. Sims' CLASSLIB used in Abstract Algebra-A Computational Approach

See https://comp.lang.apl.narkive.com/bA8Q62IO/archive-for-charles-c-sims-classlib

CLASSLIB is a libaray provides APL procedures that enables the ability doing multiple percision and symbolic computations, comparable to CAS programs such as MACSYMA of MacLisp.

Create an archive for CLASSLIB in a implementation independent format that should take trvival efforts to port to any APL2 compatible implementations (if UTF-8 is supported or encoding conversion can be done).

• convert to unicode
• write documentation
• implement SHOW function as described in Computational Algebra with APL.
