Measurements: Proof of Concept

[microbuilder]

There is a desire to introduce a standard mechanism to represent measurements in zscilib, where the following information can be specified for one or more measurement values of the same 'type':

• The specific measurement type (consisting of a base and extended type indicator)
• The SI unit and scale that this measurement uses
• The C type used to represent this measurement in memory
• Any key meta-data required to accurately interpret the measurement value(s)

It should be as concise as possible, due to memory limitations on small embedded systems, but expressive enough to communicate all essential information about the measurement value(s).

Base and Extended Measurement Types

A system of 'base' and 'extended' data types have been added via: measurement/base.h. The base groupings in enum zsl_mes_type should be reviewed for clarity and coherence.

SI Units

A first pass at representing base, derived and compound SI units has been implemented via measurement/unit.h. This list requires further review and analysis.
