/**
* Encapsulates a collection of components following the {@link GridFieldComponent} interface.
* While the {@link GridField} itself has some configuration in the form of setters,
* most of the details are dealt with through components.
*
* For example, you would add a {@link GridFieldPaginator} component to enable
* pagination on the listed records, and configure it through {@link GridFieldPaginator->setItemsPerPage()}.
*
* In order to reduce the amount of custom code required, the framework provides
* some default configurations for common use cases:
* - {@link GridFieldConfig_Base} (added by default to GridField)
* - {@link GridFieldConfig_RecordEditor}
* - {@link GridFieldConfig_RelationEditor}
