Now that we can declare tasks, it's time to think about the relationships
between tasks. For example, in a Java build, we can't JAR up our library
before compiling our sources. We model these relationships by task
dependencies and ordering.

We'll discuss three ways to configure the relationships between tasks:
`dependsOn`, `finalizedBy`, and `mustRunAfter`.
