Methods summary
`public`	# `init( )`
`protected DatabaseQuerySelect`	# `getLoadQuery( WireArray $selectors = null )` Get the DatabaseQuerySelect to perform the load operation of items Get the DatabaseQuerySelect to perform the load operation of items Parameters `$selectors` `WireArray` $items Returns `DatabaseQuerySelect`
`protected WireArray`	# `___load( WireArray $items, $selectors = null )` Load all the Fieldgroups from the database Load all the Fieldgroups from the database The loading is delegated to WireSaveableItems. After loaded, we check for any 'global' fields and add them to the Fieldgroup, if not already there. Parameters `$items` `Selectors\|string\|null` $selectors Selectors or a selector string to find, or NULL to load all. `$selectors` Returns `WireArray` Returns the same type as specified in the getAll() method.
`public`	# `getAll( )` Per WireSaveableItems interface, return all available Fieldgroup instances Per WireSaveableItems interface, return all available Fieldgroup instances
`public`	# `makeBlankItem( )` Per WireSaveableItems interface, create a blank instance of a Fieldgroup Per WireSaveableItems interface, create a blank instance of a Fieldgroup
`public`	# `getTable( )` Per WireSaveableItems interface, return the name of the table that Fieldgroup instances are stored in Per WireSaveableItems interface, return the name of the table that Fieldgroup instances are stored in
`public`	# `getLookupTable( )` Per WireSaveableItemsLookup interface, return the name of the table that Fields are linked to Fieldgroups Per WireSaveableItemsLookup interface, return the name of the table that Fields are linked to Fieldgroups
`public integer`	# `getNumTemplates( Fieldgroup $fieldgroup )` Get the number of templates using the given fieldgroup. Get the number of templates using the given fieldgroup. Primarily used to determine if the Fieldgroup is deleteable. Parameters `$fieldgroup` `Fieldgroup` Returns `integer`
`public TemplatesArray`	# `getTemplates( Fieldgroup $fieldgroup )` Given a Fieldgroup, return a TemplatesArray of all templates using the Fieldgroup Given a Fieldgroup, return a TemplatesArray of all templates using the Fieldgroup Parameters `$fieldgroup` `Fieldgroup` Returns `TemplatesArray`
`public boolean`	# `___save( Saveable $item )` Save the Fieldgroup to DB Save the Fieldgroup to DB If fields were removed from the Fieldgroup, then track them down and remove them from the associated field_* tables Parameters `$item` `Saveable` Fieldgroup to save Returns `boolean` True on success, false on failure
`public Fieldgroups`	# `___delete( Saveable $item )` Delete the given fieldgroup from the database Delete the given fieldgroup from the database Also deletes the references in fieldgroups_fields table Parameters `$item` `Fieldgroup` $fieldgroup Returns `Fieldgroups` $this
`public boolean`	# `deleteField( Field $field )` Delete the entries in fieldgroups_fields for the given Field Delete the entries in fieldgroups_fields for the given Field Parameters `$field` `Field` Returns `boolean`
