RE: SenseLab note: some updates

There is an interesting trade-off between post-coordinated and pre-coordinated
vocabularies in the clinical context.

For instance if you have the following concept fracture (site = femur,
laterality = left) this can be used in two contexts:
- In a search and exploration context, where post-coordination makes sense,
e.g., get me all diseases with site = X and laterality = Y
- In a patient encounter context, however, it would be too much to expect a
physician to document each of these (disease, site, laterality) separately in
the patient record --- requires too many clicks. A physician is perfectly happy
to click once and document "left femur fracture" ... Saves him time and
aggravation.
