addon for inheritance analysing and more

hi kasper,

i implemented following funtkionens:
.) add getter/setter generation
.) add inheritance in class model
.) add simpletype documentation on extended simpleType 
-- example: 
        <xs:simpleType name="StringLength0to256">
		<xs:restriction base="xs:string">
			<xs:minLength value="0"/>
			<xs:maxLength value="256"/>
		</xs:restriction>
	</xs:simpleType>
--> string
.) add basic class generation
.) add enumeration check and documentation generation
.) add choice check and documentation generation
.) add XSD-files location parameter in generator
.) change constructor generation disabled per default (constructor parameter setting don't works in case of class inheritance)

i hope it is in your mind
