mkindsg class to hold groups of datasets
- D24_2014 dataset on aerobic soil degradation of 2,4-D from the EU assessment as mkindsg object with metadata - f_time_norm_focus() to do time-step normalisation using the FOCUS method - focus_soil_moisture data with default moisture contents at pF1, pF 2 and pF 2.5 for USDA soil types from FOCUS GW guidance - Dataset generation scripts in inst/dataset_generation - Depend on R >= 2.15.1 in order to facilitate the use of utils::globalVariables()

+# Moisture normalisation for the other four soils is one, as soil moisture
