/** Builds images for the Grouper Training Env
* Each class has a set of images. Each class's image sets are independent, but within
* a class each image builds upon the prior exercise. Therefore all images are built
* first and then push to the repo. Order of the build is important, but ordering of the
* image pushes are not. If an image is missing the extra layers get pushed, then the
* missing layers only get tagged when they are pushed.
**/
/** Each class has a set of modules with a set of steps.
* For examples, 101.1.1, 101.1.2, 101.1.3, 101.2.1, 101.2.2, etc.
* Each step is an associated docker image.
* exceriseSets has the class name and an array of the number of steps for module.
