Find the best place to add a node, given the current state of the tree,
the constraints of the node being added, and the place where it is
going to be added.

Given an npa request, resolve it to either a single object (like a folder,
url, or git repo) or a range of manifests (a range of versions), or a
specific version (pinned or dist-tag)

1. Resolve any peer deps that each node has (to a range or single object)
2. Available options are R(all versions in range) x P(all peer deps in each)
