Added a function to MovieUtils that will rotate a 3D volume

src/MATLAB/+MovieUtils/D3dRotate.m

+function movieFrames = D3dRotate(numFrames,rotDelta,rotVec,zoomDelta,framePad,padRotOrZoom)
+    if (~exist('zoomDelta','var') || isempty(zoomDelta))

+    end
+    if (~exist('padRotOrZoom','var'))
+        padRotOrZoom = [];
+    end
+    
+    curFrame = D3d.Viewer.CaptureWindow();
+    movieFrames = zeros([size(curFrame),numFrames+numFrames*framePad],'like',curFrame);
+    clear curFrame
+    
+    frameCount = 1;
