		            This implementation is quite verbose. It will be shortened once
		            it's stable and passes all the test.

		            It's also not written with speed in mind, instead everything is
		            very seggregated, and there a several redundant loops.
		            This is to make it easier to stabilize the code initially.

		            We do a pre-pass on the first 4 rows to make some intelligent
		            guesses on the set. Guessed delimiters are in this pass counted.

		            Auto detecting delimiters
		                - If we meet a quoted string, the next symbol afterwards
		                  (that's not \s, \t) is the delimiter
		                - If we meet a date, the next symbol afterwards is the delimiter

		            Date formats
		                - If we meet a column with date formats, check all of them to
		                  see if one of the potential months crossing 12. If it does,
		                  we now know the format

		            It would make things easier to guess the delimiter before
		            doing the actual parsing.

		            General rules:
		                - Quoting is allowed, e.g: "Col 1",123,321
		                - Quoting is optional, e.g.: Col1,123,321
		                - Doubble quoting is escaping, e.g. "Col ""Hello world""",123
		                - Spaces are considered part of the data: Col1 ,123
		                - New line is always the row delimiter
		                - Potential column delimiters are , ; \t
		                - First row may optionally contain headers
		                - The last row may or may not have a row delimiter
		                - Comments are optionally supported, in which case the comment
		                  must start at the first column, and the rest of the line will
		                  be ignored
