Start working on laying out the pretend-filesystem-tree into an N-ary tree courtesy of GLib 

The basic idea is maintain a GHashTable of accounts->trees in imuse.c and allow for the getattr(2), read(2), open(2), readdir(2) calls to navigate the trees appropriately.

Take the following crappy diagram:
              Accounts/
                 |--> (d) github.com
                             |--> (f) NewEmail.template
                             |--> (d) INBOX
                             |         |--> (d) INBOX.other
                             |--> (d) Junk
                             |--> (d) Sent
                                       |--> (f) Some_Email_Subject-(2009-01-16).email

Look at muse_tree.c for more details on how I /think/ this should work

* imuse -- A FUSE filesystem for exposing IMAP accounts as a locally browsable filesystem, neat!

/*
* muse_tree:
* Defines functions for dealing with IMAP's as a GNode-based tree
*
* Abstract:
* The basic idea is to store some basic IMAP meta-data in memory as a large GNode N-ary tree:
* Accounts/
* |--> (d) github.com
* |--> (f) NewEmail.template
* |--> (d) INBOX
* | |--> (d) INBOX.other
* |--> (d) Junk
* |--> (d) Sent
* |--> (f) Some_Email_Subject-(2009-01-16).email
*
* The file "NewEmail.template" will represent a blank email and be a "special" file, whereas the
* directories will be different typed nodes in the tree, files would be another node type.
*
* This way the FUSE integration will simply need to know how to navigate these trees and parse out
* pathes in such a way that it can map back to a particular level in the tree. Operations like open(2)
* or read(2) will need to pass through to their appropriate node-type handlers (email_open(), dir_open(),
* and special_open())
