+//@function Calculates Williams Alligator indicator using SMMA (RMA)
+//@doc https://github.com/mihakralj/pinescript/blob/main/indicators/dynamics/alligator.md
+//@param source Series to calculate Alligator from
+//@param jawPeriod Period for Jaw line (typically 13)
+//@param jawOffset Forward offset for Jaw line (typically 8)
+//@param teethPeriod Period for Teeth line (typically 8)
+//@param teethOffset Forward offset for Teeth line (typically 5)
+//@param lipsPeriod Period for Lips line (typically 5)
+//@param lipsOffset Forward offset for Lips line (typically 3)
+//@returns Tuple [jaw, teeth, lips] values
+//@optimized Uses Wilder's RMA (SMMA) with exponential warmup compensator for O(1) complexity
