// Esta es la versino tiny, solko soporta 16 posiciones simultaneas
// Normale el rango para usarla es si ud en su EA suele tener entre 1-8 posiciones COMO Maximo
// a la vez.. si es conciente que puede tener mas use la version con HashMapFast donde el overhead
// de una busqueda lineal ya es mas que justificable para usar la version hashmap
// En la mayoria de casos donde solo se peude tener una op a la vez o 3-4 (casi el 80-90% de los EAs)
// Esto es mas que suficiente y mas rapido que la version con hashmap (entre 2 a 20 veces mas rapido)
