/**
* Allows for preloading various data related to the record set in single database queries, as opposed to one query per record
*
* This method will handle methods in the format `verbRelatedRecords()` for
* the verbs `build`, `prebuild`, `precount` and `precreate`.
*
* `build` calls `create{RelatedClass}()` on each record in the set and
* returns the result as a new record set. The relationship route can be
* passed as an optional parameter.
*
* `prebuild` builds *-to-many record sets for all records in the record
* set. `precount` will count records in *-to-many record sets for every
* record in the record set. `precreate` will create a *-to-one record
* for every record in the record set.
*
* @param string $method_name The name of the method called
* @param string $parameters The parameters passed
* @return void
