	Resolve a path by calling realpath and cache its result.

Detailed Description

Small helper that resolves and caches file paths.

This helps reduce the number of calls to realpath which is expensive. We assume the input are files, and cache the realpath of their parent. This way we can quickly resolve different files under the same path.
