// Build Secondary Left Navigation// Instructions for adding or deleting any navigation element
//  make sure each line starts with the single quote: (') and ends with: (' + sep +)
//  except for the last line which only requires ('  ;)
//  each line contains an ID, Hot Text and its URL
//   - the ID is the name needed to change to its state color
//     - note: ID's in the same list can NOT have the same name
//   - the Hot Text is what actually appears on the page
//     - note: If you need to use a single quote (') in the Hot Text
//             then add the \ character. It must be (\') to be treated as text only
//     - note: If you want to break some Hot Text across two lines, 
//             insert a tilde (~) between the words
//   - the URL is the destination web page from its link
