Harper + Mockingbird 0.0.2.

This release includes the following major changes:

  * `derive_more` was removed as a dependency.
  * Collections are now associated with a name.
  * Internal refactor for a new `OwnedEntry`.
  * Updated to minijinja2.
  * Undefined variables now result in errors.
  * Added a `get()` template helper with a default when undefined.
  * Added a real CLI parser.
  * Added a `time!()` macro for wall-clock time measurements.
  * Now exits with status 1 if rendering fails.
