+Creates a three-level dictionary of foreign key references optimized to speed up validation process in a form of `{resource1: { (foreign_key_field1, foreign_key_field2) : { (value1, value2) : {one_keyedrow}, ... }}}`.
 For each foreign key of the schema it will iterate through the corresponding `relations['resource']` to create an index (i.e. a dict) of existing values for the foreign fields and store on keyed row for each value combination.
 The optimization relies on the indexation of possible values for one foreign key in a hashmap to later speed up resolution.
 This method is public to allow creating the index once to apply it on multiple tables charing the same schema (typically [grouped resources in datapackage](https://github.com/frictionlessdata/datapackage-py#group))
