ries - 2018.08.05-1+b1 main

Given a number, ries searches for algebraic equations in one
variable that have a solution (root) near that number. It avoids
trivial or reducible solutions like ``x/x = 1''. If the input is
an integer, ries can find an exact solution
expressed in terms of single-digit integers.
.
The output gives progressively ``more complex'' equations
that come progressively closer to matching the input number.
