 The in-memory provider is intended to be used for testing; SDK consumers may use it for their use cases.
 Hence, the packaging, naming, and access modifiers must be set appropriately.

-- Feature Flag structure must be minimal but should help to test OpenFeature specification
-- EvaluationContext support should be provided through callbacks/lambda expressions
-- Provider must support a means of updating flag values, resulting in the emission of `PROVIDER_CONFIGURATION_CHANGED` events

+Given below are features this provider **MUST** have the following features:
+
+- The provider is be initiated with a pre-defined `flag set` provided to a constructor.
+- The flag structure must be minimalist, and should help to test OpenFeature specification.
+  - EvaluationContext support should be provided through callbacks/lambda expressions.
+- The provider must support a means of updating the `flag set`, resulting in the emission of `PROVIDER_CONFIGURATION_CHANGED` events.
+  - The change event should consider all flags changed; a union of all previous and all new flag keys should be supplied in the `flags changed` field.
+- The provider must be maintained to support specification changes.
