Release 0.0.4 delay

[Kevin Fasusi]

Unfortunately, I am running late with this release. I do not have an ETA yet, but I will post an update with this ASAP. The computation and database load times for the optimised forecast data, for the reports, are excessive. Solving this issue has slowed down the front-end development for the forecasting in the reports and subsequently the documentation. As a result of the delays, the "inventory/management policy generator," has been moved to release 0.0.5.

The good news is that the "forecasting" module, for release 0.0.4, is finished.  The reports will show simple exponential smoothing and Holts trend corrected exponential smoothing for SKUs; this functionality is also in the library API. The two forecasts also have optimised variants, using evolutionary optimisation algorithms to find the best smoothing level constants for the lowest standard error and better forecast.  In the next release, I will include ARIMA models.
