suggestion: partial verification of pacts

[ShahOdin]

Often pact files have a number of "contract"s(?) in them. It would be nice to be able to verify if a single contract is satisfied, ie a provider spec file could run:

verifyPact.withPactSource(pactBroker()).OnlyItems(1)

while debugging an individual contract, since the pact file is external and one can't simply comment or uncomment other contracts to achieve this.
