Add code to support new Con Terra input interface - including extending
the WMC class with a WMCLayer class to provide basic layer info to
use in the assocated template. Also, add code to produce and
redirect the Request object and remove code from old spec. NB, at
present the redirection URL is not correct, so the functionality
doesn't work.
