VERSION ==>                   #0.4.14
                              #UMD script

new EVENTEMITTER2.            #Like Node.js EVENTEMITTER with some differences:
EventEmitter2([OBJ])          #  - UMD
                              #  - can disable newListener event with OBJ.newListener false
                              #  - EVENT can be:
                              #     - EVENT.SUBEVENT... (depends on OBJ.delimiter (def: ".")) or [ EVENT, SUBEVENT, ... ]
                              #     - each EVENT|SUBEVENT can be wildcard "*" (if OBJ.wildcard true (def: false))
                              #        - can use EVENTEMITTER2.onAny|offAny|prependAny|listenersAny(...):
                              #          like on|off|prepend|listeners("*", ...)
                              #        - "EVENT.*" fires on "EVENT.SUBEVENT" but not on only "EVENT"
                              #     - can also use globstar **
                              #  - can use EVENTEMITTER2.[prepend]many(EVENT, NUM, FUNC): like once(),
                              #    but NUM times before removing
                              #  - if OBJ.verboseMemoryLeak true, print event name in error message when too many listeners
                              #  - faster
                              #  - no EVENTEMITTER2.EventEmitter2.listenersCount()
                              #  - with EVENTEMITTER2.emitAsync('EVENT', VAL...):
                              #     - as opposed to emit(), return listeners return values as a PROMISE(VAL_ARR),
                              #       using Promise.all()
