Adding improvement to how the infowindow width is calculated if width = 100%.
SuppressingMarkers and adding them manually to be able to control the direction steps / waypoints / markers.
Newly created markerWaypoints were same default red color, not the green A, B, … icons.
Only placing markers of waypoints along route and experimenting with onmouseover.
Trying to hide markerWaypoint and have regular placemark open up with mouseup event.
Didn't work. Trying mouseover and mouseout for markerwaypoints.
Hiding marker didn't work. Think it may be a transparent one on top of direction results one on top of place mark.
Added error handling for when startAddress is blank. Also fixed error with console.log in click of markerwaypoint.
