NEW FEATURES

    o   Add longForm() S4 generic.
	See https://github.com/waldronlab/MultiAssayExperiment/issues/333 for
	some context.

    o   Add paste2() S4 generic, with methods defined for ordinary vectors
	and arrays. Also add add_prefix() and add_suffix(), two simple wrappers
	around paste2() provided for convenience and code readability.

    o   Define setequal() S4 generic with generics::setequal as default method.

SIGNIFICANT USER-VISIBLE CHANGES

    o   Add CRAN package generics to Depends field. The default methods for
	S4 generics union(), intersect(), and setdiff() now are
	generics::union(), generics::intersect(), and generics::setdiff(),
	respectively. See '?BiocGenerics::setops' for more information.

                       Changes in version 0.52.0
