Steps to test the configfile module.

1. Check the sample configfiles in conftest. They contain random data.
2. Import the cf module into an interactive python shell.
3. Parse configfiles with cf.parse(filename)
4. parse() returns a 'node' object.
    +- Retrieve VALUES with              node.v("key")
    +- Retrieve SUBSECTIONS with         node.s("key")
    +- Return a LIST of everything in this node with             node.l()
    `- Display a FANCY TREE of this node and subnodes with       node.tree()
