The classes for testing a all in the 1 ImportXML.cs file. These can easily be broken out however is needed for production use.
I have purposely put multiple layers in the xml hierarchy to allow for many different use cases. As it is, the file is configured as such:
<Units> <- overall container for unit objects <Type typeID="1"> <- This can be a type identifier <Unit Id="1"> <- This can be a unit identifier <health>100</health> <weaponID>1</weaponID> unit stats go here.
