Functions

func CollapseLongPaths 

func CollapseLongPaths(ctx context.Context, t *Tree)

CollapseLongPaths will collapse all long chains in tree.

func CollapseLongPathsFromNode 

func CollapseLongPathsFromNode(ctx context.Context, t *Tree, nodeName string)

CollapseLongPathsFromNode will collapse current node into children as long as it has single child. Will set name of this node to joined path from roots. Will set size and heat to this child's size and heat. Expecting Name containing either single value for current node.

func SetNamesFromPaths 

func SetNamesFromPaths(ctx context.Context, t *Tree)

SetNamesFromPaths will update each node to its path leaf as name.
