# The call info visitor class does a depth-first traversal
# across a thread's call stack. At each call_info node,
# the visitor executes the block provided in the
# #visit method. The block is passed two parameters, the
# event and the call_info instance. Event will be
# either :enter or :exit.
#
# visitor = RubyProf::CallInfoVisitor.new(result.threads.first)
#
# method_names = Array.new
#
# visitor.visit do |call_info, event|
# method_names << call_info.target.full_name if event == :enter
# end
#
# puts method_names
