Add an error message if reading the input files fails #7

Closed tmaklin closed 7 months ago

tmaklin commented 1 year ago

Currently the program crashes with a segmentation fault if the input files are not formatted as expected. This isn't very helpful and it'd be better to print an error message telling that something went wrong with reading the input files.

Further improvements to add:

If the file has the wrong separator (tab instead of , for example), the files will be read in fine but they will be in the incorrect format. Should add checks for this.
Complain about the format more often.
Check dimensions whenever possible.
