Function: beep( duration )

Description: It beeps. By which I mean, it goes "BEEP", literally.

Returns: Null.

Requires module: "Beep"

Note: The beep() function does not support chaining. (One beep is quite enough.)

Example:

$A.import("Beep", { defer: true }, function() {

  // Go "BEEP"

  $A.beep(); // 0.1 of a second.

  // Or set a duration.

  $A.beep(0.5); // Half a second.

  $A.beep(1); // 1 second.

});
