Detailed Description

This is a collection of Boost units and quantities. The SI system is the base system. A dimension is composed of the base dimensions of time, mass, length etc raised to an integer power. A unit is a specific amount in a dimension (e.g. length^1) and system (e.g. since using SI it is a metre). It is instantiated as a static constant with a useful name 'e.g. metres' using BOOST_UNITS_STATIC_CONSTANT for thread safety. A quantity is an unit and a amount together (e.g. [moles, 2.0] to represent two moles).

Some fundamental SI quantities, such as length, are redefined here. This is not neccessary for C++, but allows them to be used in Python wrapping.
