respecting base element / baseURI

[btopro]

Is there any way to have this project support baseURI ? It seems like this works for hardcoded paths but not relative paths such as placing a PWA on a sub-domain when we don't know the sub-domain ahead of time. Is there a way to support this internal to lit-element-router or should we just ensure all calls to anything in routing dynamically generate this entry-way value?

#45 should resolve this. tested with and without having it set and was able to resolve to same location. Help in verifying would be appreciated.
