# Module that provides profiling of arbitrary blocks of code
module Profiling
##
# Public: Profile a given block of code. Detect any exceptions thrown by
# the block and report errors.
#
# profile_name - A name used to identify the block being profiled.
# report_kvs - A hash containing key/value pairs that will be reported along
# with the event of this profile (optional).
# with_backtrace - Boolean to indicate whether a backtrace should
# be collected with this trace event.
#
# Example
#
# def computation(n)
# TraceView::API.profile('fib', { :n => n }) do
# fib(n)
# end
# end
#
# Returns the result of the block.
