Detailed Description

Runtime counters have a two-phase lifecycle - creation and update. This is not convenient for debugging where we would like to add and remove counters with a minimum of boilerplate. This header adds a global debug runtime profile, and macros to update-or-create counters in one line of code. Counters created this way are not intended to remain in the code; they are a tool for identifying hotspots without having to run a full profiler. The AddCounter call adds some more overhead to each macro, and therefore they should not be used where minimal impact on performance is needed.
