What's Changed
This is the first release on github, but version 0.1.4
Since 0.1.3, this bumped the cachew version and removed support
for python3.7 (since it has since stopped getting support (EOLd))
Added some tests and changes to match the new cachew changes
Changed the elevation type for Location to be float, to match
the usage in here:
