Detailed Description

Class to access Lithium-Bromide solutions.

Employs some basic wrapper-like functionality to bridge the gap between the solution functions used in the paper by Pátek and Klomfar: http://dx.doi.org/10.1016/j.ijrefrig.2005.10.007

We owe gratitude to the authors for providing both access to the paper as well as the equations in the form of C source code.
