MutableHierarchicalCollection

public protocol MutableHierarchicalCollection : HierarchicalCollection

MutableHierarchicalCollection extends HierarchicalCollections to allow mutation of contents.

While many algorithms simply query the data structure in order to do their work, some algorithms modify the data structure. This protocol abstracts over a set of common mutation operations of hierarchical data structures.
