 Every library newLibrary depends on must have its own similar structure as a top-level project,
 as illustrated by dependencyLib1 and 2. Note the two level directory structure above: even if
 your library has no dependencies, the build.gradle file for the library must lie 2 directories
 below libraryBuilds1/.

-TODO: Create a script to setup the above structure.
