-Description: 
-    Facilitate the evaluation of forecasts in a convenient 
-    framework based on data.table. It allows user to to check their forecasts 
-    and diagnose issues, to visualise forecasts and missing data, to transform 
-    data before scoring, to handle missing forecasts, to aggregate scores, and 
-    to visualise the results of the evaluation. The package mostly focuses on 
-    the evaluation of probabilistic forecasts and allows evaluating several 
-    different forecast types and input formats. Find more information about the 
-    package in the Vignettes as well as in the accompanying paper,
