recode split, everything moved to a separate class, removed pointless comments
1. MotionEstimation class used in main script, to produce the output image. 2. now output image is created in directory, when the script is (no need to complicate code and create it in a customizable directory)
1. an error message is displayed when incorrect amount of command line parameters is used 2. folder of input images is specified from command line, not from config. The solution with config seems to be more confusing.
as in previous commit, remved pointless entries from config
split into separate methods, removed useless variables
removed pointless white spaces
less verbose console output
unified and more informative console printing
fixed: error after removing unused variables from config
detailed info how to use a script for printing error estimation, removed unneeded changes in other scripts.
