We change the load observations, to let us know if in some month we don't have all stations available. Also, we merge the dates at the end of the loop.

Uploaded the last version of config file. Corrected the units of load observations (x1.88). Added the option to excecute set stations. Corrected some minor errors in stadistics files

We summarized uk+loocv, all code is in uk+loocv total, an uk_repository we have fragments from the total code
