Added a working implementation of Gale-Shapley's Propose-And-Reject algorithm - Without parsing
Got rid of some comments in order to adhere to Tore's preferences
A few more sublte comments
Added parsing to the stabl-marriage implementation
Adjusted parsing of women's preferences so it adheres with algorithm
Output is now sorted by men_id before it gets printed, this way the output can be compared to Thore's provided expected output files
