[Soc-2017-dev] Daily Report - Jul 17 - Package Manager

[Ellwood Zwovic]

Today I started adding an uninstall function.

I started with the idea that a list of installed packages would be 
stored in a local "repository" (just like a remote repository) at 
install time. However, after following that idea for a bit, I felt it 
might be better for the definition of "installed" to be based on the 
presence (or absence) of the package on the filesystem. This kind of 
comes down to whether or not the package manager should be THE only way 
to install things, or if copying files into place manually should also work.

I think I like the latter approach more; it works by definition, rather 
than by design. It's also how Atom works.

A tangential question:
Can a package contain multiple "root" files? (e.g. a zip with multiple 
directories at the top level)
It would simplify things to disallow this, but perhaps some existing 
addons do this already? If so, is it worth maintaining compatibility 
with them?

Plan for tomorrow: Add file list to repo generation script, finish and 
expose uninstall function, start on version grouping.
