feat(focusUtils): A simple focus map

[tribal-mrkjffrsn]

A simple focus map that calculates element positions based on mid-pt co-ordinates.

It assumes that higher level component based focus exists and it is meant to be used within a complex component that needs it's focus map compuited on demand.

One should refrain from using this frequently as it takes a performance hit.

This implementation is a touch too simple. Not quiet effective for complex usecases
