Smoooooooth Life 50/100/200 ATF EMA

A nice, smooooth 50/100/200 EMA. This EMA can be locked to a certain timeframe and used on smaller timeframes. For example, you want data from 1H bars, but like to trade on the 15M. Well, now you can have your EMAs giving you data from that higher timeframe. I don't know how to organize the list so I'll get that fixed in a future update.
