Declare simple types for all the COBOL PIC types

[mbeckerle]

    @mbeckerle Consider declaring simple types for all the COBOL PIC types. You can carry some properties on the simple types to avoid duplication. It also makes sense to a someone familiar with COBOL. Example:

	<xsd:simpleType name="PIC9-Comp3__short" dfdl:representation="binary"
		dfdl:binaryNumberRep="packed">
		<xsd:restriction base="xsd:unsignedShort">
			<xsd:minInclusive value="0" />
			<xsd:maxInclusive value="9999" />
		</xsd:restriction>
	</xsd:simpleType>

I can see if IBM can donate the full list of simple types.
