* bug fixes
* added DMD model
* modified the `constraints` options so it now accepts of list of dictionaries of constraints with new last_window and slope options
* 'dampening' as a constraint method to dampen all forecasts, fixed Cassandra trend_phi dampening
* new med_diff anomaly method and 'laplace' added as distribution option
* modified fourier_df to now work with sub daily data
* some madness with wavelets attempting to use them like fourier series for seasonality
