Represents a single-individual word in a property name. (e.g. "my", "xml" and "parser" in a
property named "myXmlParser").
Each word contains a String value and a boolean indicating whether or not
the value is an abbreviation.
In most cases there will be no trivial way to identify abbreviations
(i.e. my_xml_parser in snake case), but for some naming conventions this may be helpful.
