*
* Farey Approximation algorithm is an algorithm to
* approximate a reduced fraction value for a certain
* decimal number x where 0 < x < 1.
*
* The algorithm works by keeping two fractional upper and
* lower bounds which start at 0 / 1 and 1 / 1. These values
* are then used to find the "mediate" which is a value between
* the two fractions.
*
* For any two fractions a / b and c / d,
* mediate = a + c / b + d
*
* Then it is checked if the decimal is greater than or less
* than the mediate and then the lower or the upper value is
* set to be the mediate respectively.
*
* This is repeated for n times and then the mediate is
* returned.
*
* This is explained in a greater detail in the "Inspiration"
* link.
