%description
Takes the outputs of a 'caret' confusion matrix and allows for the quick
conversion of these list items to lists. The intended usage is to allow
the tool to work with the outputs of machine learning classification
models. This tool works with classification problems for binary and
multi-classification problems and allows for the record level conversion
of the confusion matrix outputs. This is useful, as it allows quick
conversion of these objects for storage in database systems and to track
ML model performance over time. Traditionally, this approach has been used
for highlighting model representation and feature slippage.
