Remarks
PURPOSE: Stores multiple TGIS_FieldValueAlias items and resolves field values to display aliases and aliases back to stored values.
BEHAVIOR: Wraps an owning TObjectList-style list. ResolveGet translates stored values for display, and ResolveSet translates entered aliases back to stored values.
USAGE: Use this collection as part of a field rule.
aliases = TGIS_FieldValueAliases()
aliases.Aliases.Add(TGIS_FieldValueAlias('Active', '1'))
displayValue = aliases.ResolveGet('1')
storedValue = aliases.ResolveSet('Active')
CONSTRAINTS: The collection owns contained TGIS_FieldValueAlias items. Clone creates a deep copy of all mappings.
