# You can use this class in your console. For example
#   p = ProfilingTools.new
#   p.profiled_request(:controller => :welcome, :action => :index)
# this will profile whole application stack and save file in your tmp/profiler folder
# You can also use +request+ method just to see the output for example:
#
#   p.request(:controller => :offers, :action => :index)
#
#   p.response.body
#   p.response.cookies # and so on
