* WIP code coverage initial commit * almost works * one approach * Code Coverage * Update WebKit * it works but is not yet accurate * skip double ascii check * wrapper * it works but i'm not sure what to do about blocks * hide blocks for now * Update ZigSourceProvider.cpp * Create coverage.md * Update nav.ts --------- Co-authored-by: Jarred Sumner <709451+Jarred-Sumner@users.noreply.github.com>
