metamod:wmc_support

Since the GetCapabilities document from ncWMS contain a lot of irrelevant data, we need to generate a list in METAMOD of layers and styles that is relevant to display in WMS clients. The open WMC standard from OGC looks like the best choice for this.

The current development prototype can be found on my workstation. The structure is likely to resemble the following:
