@brief This module features subroutines that allow for the derivation of
numerous flow variables from the conservative and primitive ones.
Currently, the available derived variables include the unadvected
volume fraction, specific heat ratio, liquid stiffness, speed of
sound, vorticity and the numerical Schlieren function.
Nodes of different colours represent the following:
Solid arrows point from a submodule to the (sub)module which it is
descended from. Dashed arrows point from a module or program unit to
modules which it uses. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

@name Finite-difference coefficients
Finite-difference (fd) coefficients in x-, y- and z-coordinate directions.
Note that because sufficient boundary information is available for all the
active coordinate directions, the centered family of the finite-difference
schemes is used.
