Draws the code described in the code parameter.
code is a list of pairs of the form (binary, meta) where
binary is a string made up of 1's and 0's (1's representing black bars) and
meta is a string that is either
'' (empty string), signifying that there is nothing to be done
'long', signifying that the bars should be drawn longer than usual
or a single character string that will be printed under the bars.
drawcode returns a Draw object that is a group of the bars and the text.
