Remove redundant datatypes

[shorowit]

There are probably quite a few datatypes in HPXMLDataTypes.xsd that are essentially equivalent. It would be nice to clean it up so that the file can be significantly simplified and reduced in size.

For example:

	<xs:simpleType name="CAZDepressurizationLimit_simple">
		<xs:restriction base="xs:double"/>
	</xs:simpleType>
	<xs:complexType name="CAZDepressurizationLimit">
		<xs:simpleContent>
			<xs:extension base="CAZDepressurizationLimit_simple">
				<xs:attribute name="dataSource" type="DataSource"/>
			</xs:extension>
		</xs:simpleContent>
	</xs:complexType>

Any references to this datatype could simply use the generic HPXMLDouble instead.

Would any software developers consider this a breaking change?

@nmerket is in favor moving towards more generic datatypes. We'd like more people to weigh in if they have any concerns.
