!!Definitions and conventions

The following terms and definitions are used when describing SimTree's operation:

* Simulation parameter value set: A touple of values, exactly one for each 
  simulation parameters defined in
  a simulation study (a leaf in the simulation parameter value tree).

* Simulate run: The execution of a simulation program for one simulation parameter
  value set with the purpose of generating experimental (and eventually statistically
  aggregated) data (results).

* Collect run: The execution of a simulation program for one simulation parameter value
  set where results from one or more simulate runs are combined into final results.

* Default batches: Batch phases in a simulation run using a default start value
  for the random number generator (the so called seed index). 

* Seeded batches: Batch phases in a simulation run using user- or tool-defined start values
  for the random number generator.

* Drops: A phase were drop results are obtained. Each drop for one simulation
  parameter value set is executed with a different start value for the random
  number generator so the generated drop results are statistically independent.

* Batch results (batch result files): Results from a batch phase stored in a file.

* Export results (export result files): Internal state of the statistic sampling model components after one batch or 
  drop phase after one batch or drop phase stored in a file. Exports results are not directly
  usable by the user, they are only used as input in collect runs.

* Drop results (drop result files): Result from a drop stored in a file.

* Final results (final result file): Combined results from several batches
  or several drops stored in a file.
