ZERO-lag trader method

yet another MACD based on Mulloy's work from 1994

no warranty, use at your own risk, blah blah blah
config changes to add the ZERO-lag method

This method attempts to make the best use of
the each EMA variant, but isn't tuned (yet?)

Tinker around with the EMA weights if you want
to use it, because these weights are semi-random.

Use the values from the default config.js...
... or don't
... or do something else

but do so AT YOUR OWN RISK
