Add wrapper function and message for exact length #59

Closed jodlajodla closed 6 years ago

jodlajodla commented 6 years ago

Proposed changes:

Wrapper function which should be used in case for exactly specified length instead of passing same min and max
Message which clearly indicates that value of exact length should be passed

Coverage remained the same at 100.0% when pulling 5f11b2e9a4aedaf55521529853b531117dcfbce1 on jodlajodla:master into 48037855ba4111c954dd8723cce012ecc68bf85f on go-ozzo:master.

Just to comment on two failed jobs on Travis CI - the problem is with Go 1.6 and Go 1.7 with the following message:

# github.com/asaskevich/govalidator
../../asaskevich/govalidator/types.go:27: undefined: sort.Slice

So the proposed changes don't have any impact on this - builds would probably also fail without any changes to the package at all.

Thank you for your contribution! Because #54 handles this already, I will close this PR.
