DIY Scala Enumeration (closest possible Java Enum equivalent with guaranteed pattern matching exhaustiveness checking)

	README.txt - DIY Scala Enumeration
	Copyright (C) 2014-2016 Jim O'Flaherty

	Overview:
	Provide in Scala the closest equivalent to Java Enum
	- includes decorating each declared Enum member with extended information
	- guarantees pattern matching exhaustiveness checking
	- this is not available with scala.Enumeration
