* Add type, dispersion, min_value, max_value and other relevant internal members of MonteCarloVariable* classes to the output of MonteCarlo_Meta_data_output. Motivation is for users wanting to post-process dispersion parameters used during generation of runs * Protect against invalid memory access when length of values is zero in MonteCarloVariableRandomStringSet::generate_assignment(). Add a new verif sim warning case to cover these new lines * Update new verif data for SIM_mc_generation to support these changes Closes #1574 Co-authored-by: Dan Jordan <daniel.d.jordan@nasa.gov>

Purpose:(
|
|
Grabs a value from a data file.
|
|
The data value is located within the file at some column number and
|
|
row number.
|
|
The column number is specified for the variable.
|
|
The row -- or line -- number changes from run to run.
|
|
The file is expected to provide consistent presentation of data from
|
|
row to row.)
