Function Comparison Impact Report
This Understand iReport plugin compares functions in the current project against a comparison database and categorizes them into new, removed, and changed functions based on their
PercentChanged metric. It then recursively finds and lists all functions that call any removed or changed function, reporting them as 'Impacted Callers' to visualize downstream dependencies.
