Starting Navigation

Created:
1 navigation.php
2 navigation Array

Reasons:
1 This will house the functions for the navigation menu.
2 This will be the link structure for the navigation menu.
Need to create functions to parse it.

Modified:
1 index.php
2 readme.txt

Reasons:
1 I removed the echo's, makes the html show up better.
2 Found another typo in readme
