/**
* The validator keeps one of these classes for each resource it validates (e.g. when chasing references)
*
* It keeps track of the state of resource validation - a given resrouce may be validated agaisnt multiple
* profiles during a single validation, and it may be valid against some, and invalid against others.
*
* We don't want to keep doing the same validation, so we remember the outcomes for each combination
* of resource + profile
*
* Additionally, profile validation may be circular - e.g. a Patient profile that applies the same profile
* to linked patients, and 2 patient resources that link to each other. So this class also tracks validation
* in process.
*
* If the validator comes back to the same point, and validates the same instance against the same profile
* while it's already validating, it assumes it's valid - it cannot have new errors that wouldn't already
* be found in the first iteration - in other words, there's no errors
