- Corrected the depency for opencv bindings. Even though the library is
imported as "cv2", the package containing it is called
"opencv-python".
- pylint: ignore no-member warnings; cv2 pulls it's memebers dynamically
from the underlying libopencv, so pylint can't see them.
- Added statedetect.py in utils which is a standalone module that
contains all the methods needed for state detection
- Modified the setup() and run() methods of the GameWorkload class
in common/android/workload.py to have a parameter that enables
state checks and run the check after setup and run if requested.
State detection uses the template matching method available in
OpenCV to determine the state of the workload by detecting
predefined unique elements on a screenshot from the device.
On Unix, pip will change current working directory to whereever it has
extracted the downloaded package. On Mac OSX, it does not appear to do
that. To get around this difference, specify paths in setup.py relative
to the location of setup.py, rather than the current working directory.
