Occurrences between breaks on the first exception

[jvenki]

Suppose I have a Daily rule which occurs on all days except one day of a week and I invoke occurrences_between, the returned dates are only those till we have the exempted DAY.

require 'rubygems'
require 'ice_cube'
require 'active_support/all'
require 'pp'
include IceCube

schedule = Schedule.new(DateTime.new(2012, 05, 1))
schedule.add_recurrence_rule Rule.daily.day(:sunday, :tuesday, :wednesday, :thursday, :friday, :saturday)
occurrences = schedule.occurrences_between(DateTime.new(2012, 05, 19), DateTime.new(2012, 05, 24))
occurrences.each do |o|
    puts 'Occurring on ' + o.to_s 
end

The expected output is 19th May, 20th, 22nd, 23rd and 24th. But the actual output is only 19th and 20th. Since 21st is not allowed, the logic inside 'find_occurrences' of schedule.rb will break upon the 'res' being NULL.

For the same reason, invoking schedule.next_occurrence('20th May') will return year 2248 rather than 22nd May.
