Solver for linear systems represented as list of expressions. More efficient than using solve because it does not check that system really is linear.

lin_sol: (List F, List Symbol) -> Union(List F, failed)
lin_sol(eql, vl) solves system of equations eql for variables in vl. Equations must be linear in variables from vl.
