DID Document

This library handles the creation and update of DID documents meeting the W3C DID Document specification.

It has additional helper methods:

• addContext(): Manage information about a Verida context to a document. This adds relevant service endpoints and public keys.
• removeContext():
• addContextService():
• addContextSignKey():
• addContextAsymKey():
• signProof():
• verifyProof():
• verifySig():
• verifyContextSignature():
• locateServiceEndpoint():
