- 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.
- Modified angrybirds workload to enable state detection for
testing purposes
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.
