This is the universal identifier class for an object in the CRM-Helper system. It consists of two elements:
An optional user-friendly display name, that has no meaning to the CRM or the Helper but may be useful for
displaying to the user;
an array of app-specific name-value pairs that identify the object to each window in the system.

## Properties

- **`nativeId`** (`string`, required)
  The opaque value that identifies the object to the named system.
- **`systemName`** (`string`, required)
  Identifies the creator of the id.
