function initial() {
/*
To add a new nav item/sub nav to this
    1. add a new 'root a' var
    2. a new 'sub ul' var
    3. add a new 'display none' for the subnav
    4. add a new javascript function to the href
    5. add a new if statement seeing if the body id matches the title of the root subnav item, if it does show the subnav and change the function on the root a to a hide function
    6. add a new 'display none' to the show() function
    7. add a new 'show' javascript function to the link
That should be it, probably best to keep the same id scheme, where the a tag has an id of snxxx (sn = subnav, xxx = the first three letters of the li) and the subnav ul has the same id prefixed with a u
