[Feature] Following of links or relative links between documents doesn't work

[zeigerpuppy]

Currently, it looks like RefMD is not able to follow links between .md files.

For instance, in a tree like:

.
└── docs/
    ├── Doc1
    └── Doc2

if there is a link in Doc1: [Doc2](Doc1.md) this link does not resolve (showing "not found".

It looks like the internal RefMD references for each document are required rather than relative links.

Proposal

It would be great to be able to resolve relative links between documents to enable editing of more complex document trees.
