Refactor WSUWP New Site Administration into a class
Document the WSUWP_New_Site_Administration class
Only show network administration on the primary network
Use sites.php with a query parameter as the All Networks view

networks.php does not yet exist and we don't want to hack it in quite yet.
Add submenu items for All Networks and Add Network to Networks menu
Use Add New instead of Add Network
Add CSS handling for the new Networks menu that we introduced
Update documentation for parent_file modification
Add the  class attribute to the Add New network submenu item
Add CSS class current to Add New site
Add initial screens for My Networks and Add New Network

We're taking over sites.php and site-new.php for these screens.
Call in globals that are used to set the title and parent_file
Add the basics to our Networks page
Add the basics to our Add New Network dashboard
Slight better handling of display=network

There is no clean way to do this, but hopefully this is a less messy way.
Add handling for an add-network action on the new network screen
Add populate_network() code from WordPress 3.8-alpha to be modified
Rather than copying populate_network, use the wp_create_network() function we already have.
s/title/site_name/ when creating new site
Prefix our _create_network function with wsuwp
