[Tilecache] TileCache 2.0 Release

[Christopher Schmidt]

I'm proud to announce that TileCache 2.0 has been released.

TileCache 2.0 is a major change in that way that the code works
internally: rather than one large module each for  layers, services,
and caches, these are now split up into individual files. 

The benefit that this offers is large: it allows for much easier
customization of TileCache layer classes, with support for dropping your
own custom modules into your TileCache config for either Layers or
Caches. Additionally, it makes support for new services simpler.

As a result of this development, the following features are available in
TileCache 2.0:
 
 * ArcXML Layer
   The ArcXML layer adds support for speaking ArcXML style requests
   directly to a server. This layer type is experimental, and was
   designed and tested using the MassGIS ArcIMS server.
 * MGMaps Service
   The MGMaps service accepts requests in the format used by the MGMaps
   client, a mobile map browsing client.
 * WMTS Service
   The WMTS service is a (tile only) implementation of the current
   WMTS discussion paper release by OGC. 

In addition to simply splitting out existing files, it is now possible
to define custom module paths -- so it is trivially simple to configure
a TileCache config file to point at your own custom Python modules
installed anywhere on your system.

Beyond these improvements, TileCache is now available and installable
via Python's Package Index (aka pypi or Cheeseshop):

Information on installation via PyPI is provided in that page. (Many
thanks to Howard Butler to motivating me to put that together.)

About TileCache
===============

TileCache provides a Python-based web tile server, with pluggable caching
mechanisms, service frontends, and rendering backends. In the simplest
use case, TileCache requires only write access to a disk, the ability to
run Python CGI scripts, and a WMS you want to be cached. With these
resources, you can create your own local disk-based cache of any WMS
server, and use the result in any number of clients, including all 
WMS-C, TMS, and WorldWind clients. Development of TileCache is
supported in part by MetaCarta.
