move hardwired capacities into an input CSV file

[bstabler]

move these to a CSV file

  #through capacity per lane by fc
  thru_cap_per_lane = dict()
  thru_cap_per_lane["1"] = 1950
  thru_cap_per_lane["3"] = 1800
  thru_cap_per_lane["4"] = 1800
  thru_cap_per_lane["5"] = 1400
  thru_cap_per_lane["6"] = 1400
  thru_cap_per_lane["7"] = 1400
  thru_cap_per_lane["30"] = 1400

  freeway_cap_per_auxlane = 1200

  #turn capacity by fc
  turn_cap_per_lane = dict()
  turn_cap_per_lane["1"] = 250
  turn_cap_per_lane["3"] = 250
  turn_cap_per_lane["4"] = 150
  turn_cap_per_lane["5"] = 100
  turn_cap_per_lane["6"] = 100
  turn_cap_per_lane["7"] = 100
  turn_cap_per_lane["30"] = 100

  int_app_cap_per_lane = 1800

also update the SOABMTest inputs

compared before and after capacities. Works fine.
