get & set for the rows

[ccloquet]

Thank you for this awesome plugin !

For a project, I had to be able to modify the rows (to add/remove a class when the row is selected). I therefore added two functions :

    self.getrows = function() {
      return rows;
    }
    self.setrow = function(r, idx) {
      rows[idx] = r;
    }
    self.setrows = function(r) {
      rows = r;
    }
