HeLP + INPUT ARGUMENTS + CHECK USER's INPUT:

 - Deleted -s flag to specify if data stranded or not.
 - Substituted the argument --read-directionality by --seq-library. I think is much more intuitive and it
 is more consistent with the documentation.
 - --seq-library argument moved from options to mandatory arguments. This is a essential information and
 the output of ChimPipe will change a lot if it is wrongly set by the user. Making it mandatory prevents
 the user from just do not care about this and run it as the data were unstranded (Previously set as default).
Merge branch 'master' of github.com:brguez/ChimPipe
