The purpose of this module is to provide a simple method to do timing analysis for performance tuning of Lua-functions, that is profiling of functions. Usually measuring the duration of function calls is part of a larger effort to identify bottlenecks and problematic code. This is not a full-blown profiler, as it is not possible to do line-tracing (call-graph profiling) in the current set up. Its only purpose is to measure execution time (flat profiling), and to do this interactively from the debug console (ie. on a single function).
