depends command

[Bios-Marcel]

basically the same as scoop, with the exception of displaying a tree when running spoon depends * or passing more than one app.

Scoop currently only allows to pass a single argument and ignores everything else.

First version of this is done.

It supports single app dependency trees and reverse dependency trees. UX side of things and multi app support still missing.

Todo:

• Suggestions

  Many apps actually have suggestions that are hard dependencies if we are being honest.
  By default, we should print these too, but mark them as suggestions. Then add a flag to omit suggestions.
  All suggestions where more than option is viable, should be in one row (a,b,c)

• Guard against infinite loop, with some type of visited map
• JSON output
• Scoop compatible output
