function writeTXTtables(chanDir, fileTag, kpMat, regMat)
% writeTXTtables takes four inputs:
%       1) chanDir: string of the directory where channel data is stored
%       2) fileTag = a short string to idenitfy your text files
%       3) kpMat = the knickpoint data generated from chi_profiler.m that
%       is run during chi_profiler_STREAMobj.m
%       4) regMat = the chi regression data generated from chi_profiler.m
%       that is run during chi_profiler_STREAMobj.m
