This will simplify, through composition, a number of other
validator-formatters.
* src/validate/formatter/MultiDelimited.js: Added
* test/validate/formatter/MultiDelimitedTest.js: Added
This adds a great deal of flexibility through composition via trait
stacking.
* src/validate/formatter/UnorderedList.js: Renamed from
UnorderedListFormatter; now a trait.
* test/validate/formatter/UnorderedListTest.js: Renamed from
UnorderedListFormatterTest and adjusted to instantiate trait.
These have been refacored from the original: rather than abusing what is now
the PatternFormatter, it is now its own class.
* src/validate/formatter/UnorderedListFormatter.js: Added.
* test/validate/formatter/UnorderedListFormatterTest.js: Added.
