/**
 * Presentation-Time CPU Profiling Calling Context Tree (CCT) Node backed by the flattened tree data array in
 * CPUCCTContainer. These nodes are constructed on demand, i.e. only when the user opens some node in the CCT on screen.
 * They contain minimum amount of data in the node instance itself. As a result, a tree constructed of such nodes has
 * a very small overhead on top of the flattened data that already exists (and has relatively low space consumption and
 * construction time). The drawback is that it's difficult to add elements to a tree represented in the flattened form.
