====== ReadTouchSensor ======

The **ReadTouchSensor** function reads the state of the NXT touch sensor, which will be **true** if the switch is currently pushed in and **false** otherwise.

The **input** parameter should be an NXT input port number between 1 and 4 (which the touch sensor is plugged into).
<code>touch = nxt.ReadTouchSensor( input );</code>

====Example - Read touch sensor on port 2====
<code javascript>
function OnStart()
{
  nxt = app.CreateNxt();
  app.SetMenu( "Connect,Touch Sense" );
}

function OnMenu( name )
{
  if( name=="Connect" )
    nxt.ShowDevices();

  else if( name=="Touch Sense" )
  {
    touch = nxt.ReadTouchSensor( 2 );
    app.ShowPopup( touch );
  }
}
