* Where ever devtools is used to check input params, we should make sure the
error message is informative. This may need to change easydev itself;

Revision 1.7.3 (March 2020)
---------------------------

* fixing chembl after API changed. Fix the get_status_resources method by
removing document_term and target_prediction. Changed acd_log into alogp: for
some reasons this was changed. There was a warning on 4th March 2020 telling
that changes may occur.
