  # Provides access to Twitter's User APIs
  # 
  # Returns user instance for the <tt>id</tt> given.  The <tt>id</tt>
  # can either refer to the numeric user ID or the user's screen name.
  # 
  # For example,
  #  @twitter.user(234943) #=> Twitter::User object instance for user with numeric id of 234943
  #  @twitter.user('mylogin') #=> Twitter::User object instance for user with screen name 'mylogin'
  # 
  # Where <tt>options</tt> is a +Hash+ of options that can include:
  # * <tt>:page</tt> - optional.  Retrieves the next set of friends.  There are 100 friends per page.  Default: 1.
  # * <tt>:lite</tt> - optional.  Prevents the inline inclusion of current status.  Default: false.
  # * <tt>:since</tt> - optional.  Only relevant for <tt>:friends</tt> action.  Narrows the results to just those friends added after the date given as value of this option.  Must be HTTP-formatted date.
  #
  # An <tt>ArgumentError</tt> will be raised if an invalid <tt>action</tt> 
  # is given.  Valid actions are:
  # * +:info+
  # * +:friends+
  # 
  # +Note:+ You should not use this method to attempt to retrieve the 
  # authenticated user's followers.  Please use any of the following 
  # ways of accessing this list:
  #  followers = client.my(:followers)
  # OR
  #  followers = client.my(:info).followers
