Define boolean functions for lseg <, <=, <>, >=, >

Define close_ls(), close_lseg(), lseg_length(). Write real code for close_sb(), close_pb(), inter_sb(), inter_lb(). Repair lseg_perp() which determines if two lsegs are perpendicular. Repair lseg_dt() distance between two lsegs. Note: close_sl() is clearly broken but will repair later (calculating point on lseg rather than point on line).
