# 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
