Print Bootstrap Confidence Intervals

Description:

     This is a method for the function 'print()' to print objects of
     the class '"bootci"'.

Usage:

     ## S3 method for class 'bootci':
     print(x, hinv = NULL, ...)

Arguments:

       x: The output from a call to 'boot.ci'. 

    hinv: A transformation to be made to the interval end-points before
          they are printed. 

     ...: further arguments passed to or from other methods.

Details:

     This function prints out the results from 'boot.ci' in a "nice"
     format. It also notes whether the scale of the intervals is the
     original scale of the input to 'boot.ci' or a different scale and
     whether the calculations were done on a transformed scale.  It
     also looks at the order statistics that were used in calculating
     the intervals.  If the smallest or largest values were used then
     it prints a message 

     'Warning : Intervals used Extreme Quantiles'

     Such intervals should be considered very unstable and not relied
     upon for inferences.  Even if the extreme values are not used, it
     is possible that the intervals are unstable if they used quantiles
     close to the extreme values. The function alerts the user to
     intervals which use the upper or lower 10 order statistics with
     the message

     'Some intervals may be unstable'

Value:

     The object 'ci.out' is returned invisibly.
