profiler-tree-to-function prints a tree with root function-name whose children are the callers of function-name and their callers. Note that the tree is reversed, that is, callers appear under their callees.
profiler-tree-to-function uses the data from the previous 'profile session' with style
:tree. A profile session ends at the end of profile or when stop-profiling is called, or when the Profiler tool finishes profiling.
In both cases the counts of profile calls is the total counts of the calls to function-name. Note that the percentages (the number in parentheses) are percentages from the total number of profile calls, rather than from the numbers of calls to function-name.
