---------------------------+------------------------------------------------
A fast way to check if an expression is zero is important in many places,
see for example comment:15:ticket:11143. We should put the numerical check
mentioned there in a method (`_is_numerically_zero()`) of symbolic
expressions (`sage.symbolic.expression.Expression`).
