/**
The TimerNode class implements a tree structure where each node
represents a timer, implemented as a CactusTimer. Each node of
the tree can have zero of more children, where the names of the
child nodes are unique within a single parent, but not
necessarily unique within the entire tree. A tree formed of
TimerNode objects represents the execution profile of the
program, inasmuch as it is instrumented by timers.
Child nodes of a given name are accessed using the getChildTimer
method, where a node is created with the given name if none
exists already. This ensures that the names of the child timers
are unique.
