/**
   reads the protobuf message in [input_config_fname], which may contain submessages with
   ranges of values (indicated by presence of .upper and .lower fields, with
   .steps possible steps for each such field). The output is a message with
   the [work_unit]'th possible combination of these ranges, to the file
   [output_assignment_fname].

   Note: the range values are enumerated as if they lie on a grid with
   log-evenly distributed axis-aligned grid points, using the .base field
   as the log base for each ranged field, such that e.g. iterating over the
   range [1..8] with 3 steps and base 2 will be enumerated as (1,4,8)

   @param fname input_config_fname configuration file name
   @param output output_assignment_fname assignment file name
   @param work_unit the index of combination of range values to be used. If the
                    total of possible combinations of all fields with ranges is
   k,
                    it is guaranteed that iterating over work_unit between
   0..k-1
                    will enumerate over all possible combinations, and that
                    work_unit and (work_unit % k) will return the same output
   for
                    the same input.
   @param show_steps show the steps that occur
   @param random_seed the random seed used to initialize the IMP random number
                      generator for this simulation

   @throw IMP::ValueException if any of the values in the configuration
   file are in conflict (e.g., simulation time and maximal number of
   frames)
