    Many small improvements.
    
    * microbenchmark() now returns a data.frame instead of a matrix.
    
    * Ordering of the expression evaluation is user controllable.
    
    * A new (experimental) function is added to estimate the timing
      overhead and the granularity of the underlying timer.
    
    * The documentation has improved.

    General package improvements
    
     * The documentation has been extended and clarified in many places.
    
     * The length of the warmup phase is now user controllable using a
      'control' argument to microbenchmark().
    
     * Milliseconds are now actual milliseconds and not microseconds.

commit adf929d49ca6ae6ad2d7809b1ae8ec3d8a1fb186

    Deal with (too) fast evaluation timings.
    
    If the evaluation of an expression is sufficiently fast and the
    overhead is overestimated sufficiently, the estimate of the true
    evaluation time could be grossly exagerated.
    
    USER VISIBLE CHANGE: The microbenchmark object (a matrix) may now
      contain 'NA' values if the measured time of evaluation is smaller than
      the estimated evaluation overhead.
    
    RATIONAL: This is mainly a bugfix. In the past, this could lead to
      very large values in the result object.
    
    WHAT TO CHANGE: You may need to adjust your analysis to deal with the
      'NA' values.
