Converted into maven build-able

Added pom.xml, src/main/webapp/WEB-INF/[web.xml,cxf-servlet.xml]

The pom is configured to use the maven cxf-codegen plugin. This plugin builds java classes from the wsdl, binding.xml, and xsd files.

The package org.pesc.cds.webservice.service was added along with a WebServiceImpl class in order to have a front-end to the SOAP web service.

This particular branch (develop) has been stripped of the docs, scripts, schemas, and src/org directories.

The files in the schemas directory were moved to the src/main/resources directory.

The build.xml ant script in the scripts directory is no longer needed as the maven cxf-codegen plugin does what it used to.
