Feat/additional use cases

[SBub]

Changelog:

• frontend
  • components dir holds all reusable components across interactions
  • flows dir specific interaction flows

• service_agent

  • added support for requesting types specified in CredentialOfferCustom
  • added support for issuing multiple credentials in genericOffer

  Maybe out of scope, but what do you think

  (since generator functions are used to terminate and resume functions at will we can make cred offer tokens exchange pretty clean, but this will require some sort of a middleware to be able to pass generator functions execution context):

  
  function* issueCredentialsMaker() {
  const selectedTypes = yield createCredentialOfferRequestToken();
  const credentials = createCredentailsOfferResponse(selectedTypes);
  yield credentials;
  }

const issuerCredentailsIter = issueCredentialsMaker(); issueCredentialsMaker.next(); // server: sends to the client credentialsOfferRequest issueCredentialsMaker.next(selectedTypes) // client: sends back to the server credentialOfferResponse const signedCredentials = issueCredentialsMaker.next(); // server: sends to the client credentialOfferReceive
