// Class purpose is to queue and execute functions that are received by "EventManager":
// - allowing "EventManager" to release its event thread immediately, thus not interrupting server execution.
// - allowing us to prioritize and control execution of script functions.
// Class can use multiple threads for simultaneous execution. Mutexes are used for thread safety.
//
// 1. Hold an execution queue for scripts
// 2. Use threads to process queue, each thread executes one script function on each pass.
// 3. Catch any script error and process it
//
//
// Notes:
// * Current execution load balancing is optimized for 1 thread, and can cause unfair execute balancing between scripts.
// Not noticeable unless server is under high load.
