Benchmarks for erlang (beam) tracing

Work in progress benchmarks for erlang tracing, and methods of receiving traces e.g. receiving a trace message to a process or sending it directly to a port.

Dependencies

Kerl is required to run the benchmarks. The kerl command must be on the path and releases to be installed in the ~/kerl/ directory. Check the shell script for which releases are tested, and must be installed or deleted from the list of releases.
