Implemented the following functionality:
- added and implemented a PhotoTask asynctask to handle writing image
data to sdcard
- tested and fixed image capture routines for the back camera only. This
was a bit of a pita.
- Modified the render task in the ViewMode class to launch an
intent that will prompt which app to render with
- Modified the ThreeDimaensionalModeler class so when a user starts a
new capture process it will delete all previous files in the tmp dir.
Files will remain when app is closed or if view mode is only used for
debugging.
- added a status view in the capture class for in app debugging
- Updated ndk code to just log to the console
- Updated comments throughout
