To Fix

request handling

1. we do not need to check for GET and POST in request handlers that have only one method registered on them. eg: api.org:588 at show_users()
2. We need to check for existence of keys in request handlers, and not simply dereference the dictionary. eg: show_users()

Add user API change

We cannot create an admin user with add_user. Hence, remove the role parameter from the add_user API. make role = "user" by default.

Remove role as a parameter from the REST API. Change add_user in system interface to set role = "user" by default.

Have APIS return usage errors in JSON

wrong API usage / wrong user input should not result in 4xx or 5xx errors.

Rather, they should return a json object along the lines of

{
    status: "success" / "failure",
    [error_message: "error_string"]
    [other components on success]
}

• Errors will have "failure" and an associated error message
• Success with have "success" and other associated data
