Description

Adding environment variables to enable/disable RSU and Intersection pages

• ENABLE_RSU_PAGES: if 'false', disable RSU-specific pages, else enable
• ENABLE_INTERSECTION_PAGES: if 'false', disable CIMMS intersection pages, else enable

These variables apply to API calls, by returning empty data if the feature is disabled.
To aid in applying these features visually, components were created to handle the conditional rendering of these features. These components are:

• : renders children if RSU_PAGES are enabled
• : renders children if INTERSECTION_PAGES are enabled
• : Enables routing to child compoents if RSU_PAGES are enabled. otherwise redirects to the home page.
• : Enables routing to child compoents if INTERSECTION_PAGES are enabled. otherwise redirects to the home page.
• evaluateFeatureFlags(tag?: FEATURE_KEY): Enables filtering of records based on tag. This is intended to be used with a .filter() method. Returns false if the tag is disabled.

How Has This Been Tested?

This has been tested locally by manually adjusting the ENABLE_RSU_PAGES and ENABLE_INTERSECTION_PAGES env variables
