Fixed difference printer, where a NoneType is given into array as index if address is not found
Created a small script to extrude data from data folder where test logs are found to diffs folder where the output will be put
Externalized get_data_diffs function to CANDiff class, since it crunches differences and returns objects rather than simple string
Added a function for using the externalized CANDiff function (mentioned earlier) to build a string
Added csv matrix creation function
Implemented save as csv function and refactored save as text and other minor function
PEP8 for differ and new function
Clean ups and fixes for data structures: CANData - fix initializer with regressive unneeded parameters; also somehow tuple turned to 2, where it shouldn't
In CANNode removed dict structure and left an array of CANData, added a new function for checking if specified address has data
Made a universal function for retrieving data via addresses
