############################################################################
# FEATURES:
# - create pins and their elements
# - sort pins alphabetical
# - swap words of the pinlabels
# - negation lines if label is in "_","\" is for escape
# - rotate top and bottom pinlabels if wished
# - if the symbol's width specified is 0, then tragesym calculates the
# symbol width based on the greater number of pins at the top or at the
# bottom of the symbol
