Code to generate navigation

I will probably change this to search for Networks that are
of a type == reservation and member of a specially named pool.

I'm thinking of naming that pool 'Allocations'.
Show the pool Allocations' members in navigation
Cleanup of javascript and layout

* Load a jquery object for the map only once, then reuse that object.
* Do the same for the loadTopLevel function
* remove the clearData() function, since it was only containing 1 call
* widen the slider. Still need a catching phrase to describe it.
* Add a small divider at the top.
remove some unused code
Add some room below the map
