versions.gradle

/**
 *Source largely taken from this OS repo: https://github.com/googlesamples/android-architecture-components/blob/master/GithubBrowserSample/versions.gradle
 * Thank you to everyone involved in this awesome OS project!
 *
 * In this file, we basically build a tree of deps in a very DRY way.

//ext is a way to add extra data key/value pairs to a gradle domain object. Since it has no prefix,
//it is short hand for project.ext in this case.
//[:] is groovy syntax for creating a "Map" Object, which is a collection of key/value pairs

//create a map of key/value pairs, called deps (deps)
ext.deps = [:]

//def means we're making a local variable. We'll use this map to build our deps key/value
//pairs below
