* algebra/alql.spad.pamphlet (IndexCard): Now satisfies
CoercibleFrom String. Remove explicit coerce export.
* algebra/carten.spad.pamphlet (CartesianTensor): Remove explicit
coerce export. Add satisfaction of CoercibleFrom appropriate
domains.
* algebra/color.spad.pamphlet (Palette): Relace explicit coerce
export with CoercibleTo %.
* algebra/constant.spad.pamphlet (InnerAlgebraicNumber): Likewise.
* algebra/dpolcat.spad.pamphlet (DifferentialVariableCategory):
Likewise.
