Testing adding the ability to show directions to here feature at the top of each placemark.

The directions will be displayed either right after the map-canvas or wherever their exists a <div id="simplemap-directions"></div> element on the Wordpress page.
Set directionService later as "google.maps" was undefined at the variable initialization stage.
Set directionsResults later as $('#simplemap') is not yet defined at the point of initiation.
Page is not using jQuery so have to add simplemap-directions div to page via pure javascript.
Corrected directionsResults logic.
Removing jQuery/$ references and using regular javascript.
Adding troubleshooting to see if click event is firing.
Using full jQuery, it's just that '$' is not available as a shortcut.
Added computeDirections.
Fixed function definition.
Corrected objects that were not actually children of map object.
