How do I create dependencies between feature flags?

LaunchDarkly has a feature called prerequisites, which lets you determine which flags must be on or off before another flag’s targeting rules apply.

For example,  you could have a flag that controls the visibility of a “sign up form” and then two other flags that control elements within the sign up form.  In LaunchDarkly, you could create a prerequisite that ensures that the sign up form flag must be on before a dependent flag is evaluated.
