# The class that encapsulates creating a Pivotal Tracker Feature Story
class GitPivotalTrackerIntegration::Command::Newfeature < GitPivotalTrackerIntegration::Command::Base

  # Creates a Pivotal Tracker story by doing the following steps:
  # * Takes arguments from command line
  # * If arguments contains -i then it creates a feature story under icebox
  # * If arguments contains -b then it creates a feature story under backlog
  # * If arguments contains -tl then it creates a feature story at top of specified list
  # * If arguments contains -bl then it creates a feature story at bottom of specified list
  # * If arguments contains -p1 then it creates a feature story with estimate as 1 point.
  # * If arguments contains -p2 then it creates a feature story with estimate as 2 points.
  # * If arguments contains -p3 then it creates a feature story with estimate as 3 points.
  # * If there are no arguments passed then it creates a feature story in icebox top of the list if you wish to create
