The function looks in the output folder and collects all model objects given
pattern and collates them into a single .csv file for easy

unique parameter names and match parameters from all models to the vector.
This ensures that the same parameters from different models are in the same
row in the output file.
collate(path = NULL, pattern = NULL, digits = 4)
The relative path (from working directory) to the folder where the outputs are stored. Default is NULL, which means outputs are found in the root working directory
A regular expression. Only file names which match the regular expression will be returned.
An integer giving the number of digits to round results
