Data Types
type	tree_amg_aggregate::tamg_agg_monitor_t

Modules
module	tree_amg_aggregate
	Implements an aggregation for TreeAMG hierarchy structure.

Functions/Subroutines
subroutine	tree_amg_aggregate::aggregate_finest_level (tamg, lx, ly, lz, ne)
	Aggregaiton on finest level Aggregates all dofs in an element into a single aggregate.
subroutine	tree_amg_aggregate::agg_greedy_first_pass (naggs, max_aggs, n_elements, facet_neigh, offset_el, n_facet, is_aggregated, aggregate_size)
	First pass of a greedy aggregation Loop through all dofs and aggregate on dof that has all unaggregated neighbors.
subroutine	tree_amg_aggregate::agg_greedy_second_pass (naggs, max_aggs, n_elements, facet_neigh, offset_el, n_facet, is_aggregated, aggregate_size)
	Second pass of a greedy aggregation Loop through all unaggregated dofs and add them to a neighboring aggregate. If no neighboring aggregates, create a new aggregate.
subroutine	tree_amg_aggregate::agg_fill_nhbr_info (agg_nhbr, n_agg_nhbr, n_elements, facet_neigh, offset_el, n_facet, is_aggregated)
	Create information on which aggregates are "adjacent" to eachother.
subroutine	tree_amg_aggregate::aggregate_greedy (tamg, lvl_id, max_aggs, facet_neigh, agg_nhbr)
	Aggregates dofs based on adjacent dofs.
subroutine	tree_amg_aggregate::aggregate_end (tamg, lvl_id)
	Aggregate all dofs to a single point to form a tree-like structure.
subroutine	tree_amg_aggregate::aggregation_monitor_finest (lvl, ndof, nagg)
subroutine	tree_amg_aggregate::aggregation_monitor_phase1 (lvl, ndof, nagg, is_aggregated)
subroutine	tree_amg_aggregate::aggregation_monitor_phase2 (lvl, ndof, nagg, is_aggregated)
subroutine	tree_amg_aggregate::aggregation_monitor_final (lvl, ndof, nagg)
subroutine	tree_amg_aggregate::aggregate_pairs (tamg, lvl_id, max_aggs, facet_neigh, agg_nhbr)
	Aggregates pairs of dofs based on adjacent dofs.
