Add a Resolver function to the DID Class

[JelleMillenaar]

Description A DID is an identifier that must be able to resolve to a DID Document. This functionality already exists in the DID Document class.

Requirements

• [ ] Create a Resolve function in the DID Class
• [ ] Load a DID Document via the DID Document class (If it isn't cached)
• [ ] Optionally cache the DID Document in the DID class (Parameter cache : boolean = true).
• [ ] Return the result in JSON?

Additional Info This function is ment to return different thing: DID Documents, public keys, service endpoint results etc... We need to consider how we catch all that. Might want to research how universal implementations do it.
