1.13.0

New feature:

Indicators can now be generated as an extension method of history. - #463
Please note this is not a breaking change as the original syntax still works as previously specified.

// existing original syntax
var results = Indicator.GetEma(history,lookbackperiod);

// newly added extension syntax
var results = history.GetEma(lookbackPeriod);

Documentation now shows the new extension approach syntax only.
