// Package factions provides comprehensive faction management for the EQ2 server emulator.
//
// The faction system manages relationships between players, NPCs, and various game entities.
// It includes consideration levels (con), hostile/friendly relationships, and dynamic faction
// value changes based on player actions.
//
// Basic Usage:
//
// // Create a new faction
// faction := factions.New(db)
// faction.ID = 1001
// faction.Name = "Guards of Qeynos"
// faction.Type = "City"
// faction.Description = "The brave guards protecting Qeynos"
// faction.DefaultValue = 0
// faction.Save()
//
// // Load an existing faction
// loaded, _ := factions.Load(db, 1001)
// loaded.PositiveChange = 100
// loaded.Save()
//
// // Delete a faction
// loaded.Delete()
//
// Master List Management:
//
// masterList := factions.NewMasterList()
// masterList.AddFaction(faction)
//
// // Lookup by ID or name
// found := masterList.GetFaction(1001)
// byName := masterList.GetFactionByName("Guards of Qeynos")
//
// // Add relationships
// masterList.AddHostileFaction(1001, 1002) // Guards hate bandits
// masterList.AddFriendlyFaction(1001, 1003) // Guards like merchants
//
// Player Faction System:
//
// playerFaction := factions.NewPlayerFaction(masterList)
// playerFaction.IncreaseFaction(1001, 100) // Gain faction
// playerFaction.DecreaseFaction(1002, 50) // Lose faction
//
// // Check consideration level (-4 to +4)
// con := playerFaction.GetCon(1001)
// if con <= factions.AttackThreshold {
// // Player is KOS to this faction
// }
//
// The system integrates with the broader EQ2 server architecture including database
// persistence, client packet updates, quest prerequisites, and NPC behavior.
