Variables
size_t	min_equalize_size = MIN_EQUALIZE_SIZE
	minimum number of object that should be attained (in at least one node) before equalizing (load-sharing) bewteen nodes.
float	equalize_inbalance = EQUALIZE_INBALANCE
	maximum imbalance between nodes (max_obj - avg_obj)/max_obj allowed before equalizing.
float	min_equalize_step = MIN_INBALANCE_STEP
	minimum jump in equalize before breaking
bool	equalize_children = true
	if true, equalize the number of children. Otherwise equalize the number of objects.

function to apply a dynamic to a wave function distributed accross multiple nodes

Parameters

[in]	iteration	wavefunction that the dynamic will be applied to.
[in]	rule	dynamic that will be applied.
[out]	next_iteration	wave function that will be overwritten to then contained the final wave function.
[out]	symbolic_iteration	symbolic iteration that will be used.
[in]	communicator	MPI communcator.
[in]	max_num_object	maximum number of objects to be kept per node, -1 means no maximum, 0 means automaticaly finding the maximum ammount of objects that can be kept in memory.
[in]	mid_step_function	debuging function called between steps.
