method "void startAt (float x, float y, float z)" at missionSpec could have the pitch (and the yaw) parameters as in the .xml file

[jorallo]

The XML file allows for AgentStart with four parameters, as follows:

<AgentStart>
<Placement x="100.5" y="226" z="97.5" pitch="50"  yaw="0" />
</AgentStart>

But the method only allows 3.
Of course, we can specify a pitch (and the yaw) through the XML file and even do this for multiple task generators where the start position changes with the instance, by inserting a variable string into the file, but at some point it would be handy to have the pitch (and also the yaw) parameter as well in the startAt method.
