Adjusted the getOrientation of agentService to
inject the window instead of calling for it in
agentService. Also adjusted treeNodeController
for this. Added tests for the agentService's
getOrientation function.
Added tests inside spec files
for the QueryService, TreeNodeController,
and InfoGesture. Also cleaned up the
tree so that padding is used between
buttons instead of margins.
