This adds numerous technical analysis algorithms:
* exponential_moving_average
* double_exponential_moving_average
* triple_exponential_moving_average
* relative_strength_index
* triple_exponential_average
* kaufmans_efficiency_ratio (commonly referred to as just "Efficiency Ratio")
* kaufmans_adaptive_moving_average
* chande_momentum_oscillator (both the common 'smoothed' version, and the ta-lib version)
