Instead, we just prepend/append to transform lists as needed. Maybe this
is less confusing.

Move emptyRead to a higher visibility scope, and make it handle caching
metadata in addition to reading galleries. Caching still leverages
memGallery since re-implementing a cache just for FileLists would largely
be redundant.

Split downloading the MEDS dataset to a separate file

downloading all the datasets in downloadDatasets.sh is time consuming, and
MEDS is the only dataset used in make test, as well as
evalFaceRecognition-MEDS.sh. Splitting MEDS to a searate file simplifies
the process of validating an OpenBR build.

Added training for cascade classifiers

Cosmetics, used QProcess instead of system, used File::contains and
File::get, eliminated RectToString()

It looks worse than it is. De-indented some code, that’s all…

Tabs to spaces, used OpenCV folder separator function, capitalized
struct name, re-added missing bracket

Needs to be documented
