A solver for arbitrary systems of linear equations

This piece of C99 code is a set of rudimentary functions for manipulating
linear functions of an aribtrary number of coefficients. This includes
a function for solving systems of an arbitrary amount of equations using
the substitution method.
Note that I aimed for the absolute best elegance of the code rather
than performance, which would require additional "if" checks, function
