Release Name: 0.2.0

Notes:
Monkeys are cool.


Changes:
added options to new(): 
  sep_string - specify the separator that 
               defines a "line", defaults to $/.
  recycle - causes randomline and randomlines
            to reload the index (quickly, by
            copying the line based index)

new methods: 
  length - returns the number of lines left 
           for randomline and randomlines
  r_eof? - returns true if randomline(s) is
           out of lines.
  randomlines(x) - returns x random lines.

more tests were added as well.
