<Example taken from the Broadside.MIS file.>
instant SimGroup "LowerElevator" {    // Sim Group.
 instant SimPath "Path1" {          // Sim Path. Markers go inside.
   instant Marker "Marker1" {       // Marker 0.
     dataBlock = "PathMarker";
  };
 
  instant Marker "Marker1" {      // Marker 1
     dataBlock = "PathMarker";
  };
 };
 instant Moveable "elevator_8x41" { // Object to move. MoveObj.
 };
};

If MoveObj is an elevator then the MoveObj will be set to Marker0
position. The elevator Starts at Marker0 and moves to Marker1 then
Marker2 and so on till hit its the top.  After hitting the top it
moves back to Marker0 passing through all other Markers. There are
Flags you can set in the instant Moveable data block area. If power
is lost then the elevator will return to Marker0.
Must set the following to 1 for it work:
loop   The elevator will move without being triggered.
stopWayUp - Will stop at all Markers on the way up.
stopWayDown - Will stop at all Markers on the way down.
noTeam - Any team can trigger the elevator.
triggerHit - Elevator must be triggered by an external object.

If MoveObj is a Door then the door will be set to the center
Marker. Example: You have Rdoor and Ldoor. In the SimPath you have
Marker0, Marker1, and Marker2. The doors will start at Marker1. When
opened the Ldoor will move to Marker0 and Rdoor will move to Marker2.
