%description
A minimalistic but flexible framework that facilitates the creation,
management and training of multiple 'caret' models. A model grid consists
of two components, (1) a set of settings that is shared by all models by
default, and (2) specifications that apply only to the individual models.
When the model grid is trained, model and training specifications are
first consolidated from the shared and the model specific settings into
complete 'caret' model configurations. These models are then trained with
the 'train()' function from the 'caret' package.
