Griffin Legal persons API

In the Griffin API, your organization and your customers are all represented by [legal persons](/docs/terms/legal-person). When you sign up with Griffin, your organization will be automatically assigned a unique legal person ID. When onboarding your customers, you will create legal persons to represent them. Every legal person has a `legal-person-type` with the value: `individual` or `corporation`. An `individual` represents an individual human. A `corporation` represents any non-human entity (not just companies). A corporation should have at least one [director](/docs/terms/director) or [person with significant control](/docs/terms/person-with-significant-control) attached to it, who must also be represented as a distinct `individual` legal person.
