Issue #5 resolved

Jed Wesley-Smith created an issue 2013-07-30

need to check all parameters for co and contravariance

orElse(Option<A>) in particular needs to move as the overloaded orElse(Supplier<Option<A>>) no longer works due to Option extending Supplier

actually changes the API, perhaps a better solution is for Option to not extend Supplier, still a binary API breakage, but possibly worthwhile

fixed in version 1.3 or possibly 2.0 as it changes API of Option (no longer extends Supplier)
