Detailed Description

A unit is the definition of a reference quantity to measure a dimension. For example, second or ampere.

Units are independent C++ classes which are required to present a minimal interface:

• symbol of the unit, as a static constant string
• name of the unit, as a static constant string

Here "string" is intended as an object convertible to std::string and which itself exposes a std::string-like behaviour.

Although units can be derived from UnitBase, there is currently no necessity to do so since no part is shared. UnitBase is therefore provided as an example implementation.
