* Update the dangerfile * Make a trivial change to test new dangerfile * Try out the new value with another trivial change * Add a configuration API to make a unified place for pulling config from clients safely * Specify properties for delegate * Finish removing text experiment global enable * Generate the config file * Clean up configuration to fix tests * Work on making it serializable * Finish it up * Fix example code * Update sample project * Clean up a few things * Align with new project order * Make it faster and update license header * Add an option to specify your config at compile time * Update another license header * Add a version field, and bring interface state coalescing into configuration * Update CA queue code * Update CATransactionQueue tests * Turn transaction queue on by default (for now, see comment) * Update the tests * Update the tests AGAIN * Remove unused ordered set
