src/erltrek_scan.erl

* Use erltrek_calc functions of in_quadrant/{1,2}, in_quadqc/1
  and in_sector/{1,2}, in_sector/1
  as the substitute for the macros ?INQUAD/1, ?INQUAD2/2, ?INQUADQC/1
  and ?INSECT/1, ?INSECT2/2, ?INSECTSC/1
Update src/erltrek_calc.erl

* Define functions of in_quadrant/{1,2}, in_quadqc/1
  and in_sector/{1,2}, in_sector/1
  as the substitute for the former macros
  ?INQUAD/1, ?INQUAD2/2, ?INQUADQC/1
  and ?INSECT/1, ?INSECT2/2, ?INSECTSC/1
  (To facilitate dialyzer's type detection)

* Use the above functions to substitute the macros as well
Update erltrek.hrl

* Remove quadrant/sector boundary macros, substituted in the related functions at erltrek_calc module
