This release contains changes associated with the following GitHub issues:

#19: Correct PHP notices generated.
#20: Display "New version available" only from admin's Modules->Shipping
#21: Correct "Next Day Air Early" quotes not being returned.
#22: Restructure distribution.
#23: Sort quotes returned by cost.
