Version 4.2.1     2014-07-30
----------------------------

This is not backwards compatible because functions keywords where renamed

Features:

   * BenchmarkIT
      - Support for selected code parts within a function using: START/END TAGS as Comments
         START-TAG: # ::SPEEDIT::
         END-TAG: # **SPEEDIT**

      - option: check_too_fast for very fast code this can be enabled to raise an Exception if it is faster than a reference code

   * MainCode.speed_it(): added new keywords so that all can be enabled/disabled from this one function

   * ProfileIT
      - new keyword: profileit__repeat: which repeatedly profiles the function and generates one report

Fixes/Improvements:

   * BenchmarkIT
      - added variable name prefix to avoid potential name clashes: reserved prefix: '_speeit_prefix'
