[Ves] Trying to compile PointCloudStreaming

[Lynn Gilbert]

I got a chance to look at this a bit more. The function lfind was 
"extern"d in tiffiop.h (vtk-android) and defined in KiwiNative.cpp 
(Apps/Android/Kiwi). The problem was that PointCloudStreaming.cpp 
(Apps/Android/PointCoudStreaming) can see vtk-android but can't see the 
definition of lfind in KiwiNative so the linker is erroring because it 
can't find a definition for lfind. I copied the definition from 
KiwiNative.cpp to PointCloudStreaming.cpp and it worked fine.

In addition, I fixed my earlier compilation error with 
vesKiwiText2DRepresentation. I changed:

   vesKiwiText2DRepresentation* mText;

to

   vesKiwiText2DRepresentation::Ptr mText;

I've attached my latest PointCloudStreaming.cpp file. Feel free to 
review and make any additional changes (i.e. remove comments, move the 
lfind definition, etc.) before checking in.

Thanks!
Lynn
