23  * Brief description: Implementation of a ns2 movement trace file reader.
24  *
25  * This implementation is based on the ns2 movement documentation of ns2
26  * as described in http://www.isi.edu/nsnam/ns/doc/node174.html
27  *
28  * Valid trace files use the following ns2 statements:
29  *
30  * $node set X_ x1
31  * $node set Y_ y1
32  * $node set Z_ z1
33  * $ns at $time $node setdest x2 y2 speed
34  * $ns at $time $node set X_ x1
35  * $ns at $time $node set Y_ Y1
36  * $ns at $time $node set Z_ Z1
37  *
