[@http://en.wikipedia.org/wiki/Fundamental_units units] obey the rules of a specific algebra.
We will refer to a pair of a base dimension and a rational exponent as a *fundamental dimension*,
and a list composed of an arbitrary number of fundamental dimensions as a *composite dimension* or, simply,
*dimension*. In particular, given a set of [$../../libs/units/images/form_0.png] fundamental dimensions
denoted by [$../../libs/units/images/form_1.png] and a set of [$../../libs/units/images/form_0.png]
rational exponents [$../../libs/units/images/form_2.png], any possible (composite) dimension can be written
as [$../../libs/units/images/form_3.png].

Users of a dimensional analysis library should be able to specify an arbitrary list of fundamental dimensions to
produce a composite dimension. This potentially includes both repeated tags and dimensionless tags. For example,
it should be possible to express energy as [$../../libs/units/images/form_9.png], [$../../libs/units/images/form_10.png],
[$../../libs/units/images/form_11.png], or any other permutation of mass, length, and time having aggregate exponents of

1, 2, and 2, respectively. In addition, in some cases, multiple distinct fundamental dimensions representing the same dimension
measured in different unit systems may appear. In order to be able to perform computations on arbitrary sets of dimensions,
all composite dimensions must be reducible to an unambiguous final composite dimension, which we will refer to as a

This library is designed to support arbitrary value type algebra for addition, subtraction, multiplication, division, and
rational powers and roots. For compilers that support `typeof`, the appropriate value type will be automatically deduced.
