% token=readtokn(fileID)
%      Returns the next token from the file pointed to by fileID.
%      Tokens are separated by whitespace.
%      A comment starts with a '#' and ends at the end of a line, and
%      is treated like whitespace.
%      The token is returned as an array of characters.

while ~finished

  % So, what does this char represent?
  if char=='#' % Skip to end of line
