Add unit test for wrapper array
Address issues #17 and #18

Definitions for elements derived from complexTypes (in types section)
will have camelCase names

Add DocumentLiteralWrapperClient, a convenience wrapper for SoapClient
when using wrapped document/literal. Allows usage of methods like
rpc/*, by wrapping params to a single object.
Example of usage in client document_literal:simple, though commented
out by default.

Update DocumentLiteralWrapper to unwrap simple arrays
Add additional tests for DocumentLiteralWrapper

Add expected request/response sampleXML to wrapped document/literal examples,
to help clarify what is expected of wrapped document/literal

Fix issue with MethodParser and newlines (experienced on Windows)
Address issue #17

This change removes nesting of arrays, and removes rending of ArrayOf*
Update examples with the usage.
Unit Tests stay the same, because the ArrayOf structures still get
generated, they just don't get rendered.

It would be good to have unit tests that test actual SoapServer responses
