Structs
ReaderParams tells us what our reader should be doing.
delimiter - the delimiter that tells us what our data fields are seperated by
skip_header - an optional field that tells us whether or not we should skip so many lines that are not
comment lines from the beginning of the file
skip_footer - an optional field that tells us whether or not we should skip so many lines that are not
comment lines from the end of the file
usecols - an optional field that tells us what column numbers we should be using from the data field
max_rows - an optional field that tells us the maximum number of rows we should use from the file
A structure that contains all of the results. It tells us the number of fields we had
along with the number of lines that we read. Finally, the results are stored in a single Vec of
type T. Type T is dependent on what was supplied to ReaderParams for dtype.
Enums
The type of delimiter that we can use
Functions
It simply reads all of the lines in the file when an end of line is denoted by \n.
A comment character is provided and if it is seen then it is not counted in the total.
Note it is assummed that the comment character only appears at the beginning of a line and nowhere else.
If it does appear in more then one location this will currently provide the incorrect number of lines per
the file. A more careful solution could be introduced which does not take advantage of this quick method.
It simply reads all of the lines in the file when an end of line is denoted by \n.
It does not take into account whether any line is a comment or not.
