Iterative Root Finding via Steffensen's Method

public defn steffensen-method (f:(Double) -> Double, x0:Double, step:Double = ?, eps:Double = ?, max-iter:Int = ?) -> Double

f: (Double) -> Double - Function f(x) for which we will find a zero
x0: Double - Starting X location
step: Double - Size of the step used for computing the derivative of f numerically. The default value is 0.001
eps: Double - Epsilon is used to determine when to stop iterating, We compare f(x) to this eps value and if |f(x)| < eps we stop iterating. Default value is 0.01
max-iter: Int - Maximum number of iterations to attempt. This prevents the solver from getting stuck looking for a solution. Default value is 1000
Returns Double - Value of x that approximates a zero in f(x)
