Add usage advice on 'composed primarily of'

[pbuttigieg]

Hi all, this issue follows a call for clarification over at EnvironmentOntology/envo#768

In summary, when CPo is used between an environmental material (like a portion of liquid water) and a CHEBI molecular entity (like water), it can be misread as: "the mass of the material is mostly made up of one molecule of water".

In initial discussion with @cmungall, the relation is more about being primarily composed of at least one instance of the range class.

Could a comment or other suitable annotation be placed on the CPo object property to clarify this?
