Create high level workflow for how information is going to be exchanged between user and consumer

[JakeRaffa]

• [x] create Json doc that has each piece of information that a patient might need
• [x] figure out how we are going to allow the user to send information to the consumer
• [x] if consumer requires a certain document, figure out how to grant requirement

[JakeRaffa]

Our idea:

• A consumer requests certain pieces of information, and the user gives “links” to that data within their DID document
• We also create a registry that stores what pieces of information the user allowed the consumer to access
• Every time a consumer needs certain data, they go through a function in UserRegistry contract (or some new contract that we create), and that function checks whether the consumer is allowed to get that data
• If it is allowed, the data is returned, otherwise access is denied.
