We need a way to diagnose what kind of phone movement causes bluriness in recorded images. So, we'll record all sorts of sensor data to determine the orientation and movement of the phone at every point in time, and save all that to a csv to be analysed locally.

TLDR: record android sensor+orientation+movement data to .csv file

Using the .csv file created for #1, we will use the video recorded for this issue to figure out
what kinds of phone orientation and movement are responsible for blurry video.

We need to take many photos in sync with sensor data capture. We need these sensor-synchronised-images so that we can correlate sensor readings to image blurriness and then come up with an algorithm that filters images based on corresponding sensor readings.

To that end, I will convert this app into one that take many pictures repeatedly and saves them to disk while at the same time taking and saving sensor readings. The photos will be named the time at which they were taken so they can be associated to sensor readings that were recorded and saved at the time of their being taken.

we want to be able to add random code to the 'main method' of this app fairly often - usually code that writes sensor data to files or something like that. This code is not intended for the final version of the application, and so we should not be adding this code to the 'production' version of the source code for this project.

Therefore, we will create a 'debug' 'build variant' of the project - a 'debug version' of the code that can be built instead of the main version by specifying setting and/or arguments to gradle.
