title: Displaying an indoor building map with route tracing draw path to rooms
body: <p>I need to display a map of multi-level building on a website. This website will only be displayed on a PC in the foyer of this building.</p>
  
  <p>I need to allow people to do a room search and then draw directions to the room on the map. I also need people to zoom and drag the map too.</p>
  
  <p>I have watched the Google "Map your business, inside and out" video and can see a lot of that could be useful, but there is nothing there to be able to show directions from one room to another.</p>
  
  <p>So before I spend a lot of time writing my own code using jQuery, I was wondering if anyone else has done something similar, or if anyone can suggest some good starting points?</p>
