Fixed the Sentence class. It is now a real list. Before, it stored both a list class and just a list... It was double at least. Now it is fixed and it still works.

Added the mistake_finder.py (forgot in last commit). Used for filtering out the mistakes. Skeleton now. Integrated its call in statistics.py for the Anchor Algorithm (commented out now). Small PEP8 change in anchor_algorithm.py.

Moved the faster file selection functionality to this branch. Now moving all my edits to the master is done.

Added the mistake_enum.py (Enum for the type of mistakes, to mark words with) and added mistake properties/getters/setters in words.py.

Changed such that words are now paired, and removed the need to keep passing the same arguments around that were not updated, only read from.

Added functionality and removed a function that was repeated in source word, but also inherited from word

Changed the reading such that shadow and source can be compared again. Now only the first ones are picked. For now, this is fine since the model can only handle two files, but needs to be changed in the future.

anchor_algorithm called source and shadow as parameter or as 
self._source/shadow interchangably. This is now unified as self._source 
and self._shadow everywhere.

Fixed .csv writing, should now work. Rummaged in view to make both writers selectable, but decided to keep it for next sprint maybe.

Data update

Continued last night's update. Sentence now extends list so that it can be used in the same way as the list of Words that was previously used. Emma's strategy has been adapted to work with the new structure. That just leaves Thijs's strategy.

See merge request !40

Debugged I/O class. It works in the sense that it performs CSVreading and txtwritingdecently. Next up: finding format that I can write to NICE .txts and to .csvs

Added .csv as explicit default file type for file selection, some syntactic and spelling improvements.

Introduced additional elegant type checks (source/shadow) and fixed an error introduced through previous commit

'Uncluttered' action-value pair splitting in actionlistener and adapted filereader call according to expected new structure.

Updated the bookkeeping of which words are shadowed to account for gaps, otherwise errors would occur

Removed the functions to calculate the latencies and mistakes as they relied on the old frame which is deprecated.

The way it is currently fed to extract_data and df_to_words will not work, this needs to be looked at.
