* Update stats for algorithms using EMA
* Update failing unit tests
- Indicators with name starting with A;
- `Maximum`. `Minimum` and `MACD`;
- Adds new unit test method to `CommonIndicatorTests`: `WarmsUpProperly`;
- Indicators unit tests inherit from `CommonIndicatorTests`.
- `IIndicatorWarmUpPeriodProvider` represents an indicator with a warm up period provider.
- `SimpleMovingAverage` and `ExponentialMovingAverage` implement `IIndicatorWarmUpPeriodProvider`.
Add the following methods corresponding unit tests to QuantConnect.IndicatorExtensions:
*EMA()
*MAX()
*MIN()
*SMA()
Add method to calculate default smoothing value for an EMA indicator
