//: This is based on Vincent Pradeilles' NSSpain 2018 lightning talk. I tried to find a way around using a 
//: custom operator for this because I haaaaate custom operators, but everything else I tried just led to 
//: more callback hell.
//:
//: Custom `infix` operators allow you to pass the left hand side and right hand side of the operator as 
//: the first and second parameters of a function. I couldn't figure out how to make a function which did that.

/**
 A swift protocol to make any Int enum able to count its cases.
 
 Super-useful for making enums to help you deal with sections in tableviews without having to maintain a case for the count of the enum.
 
 Originally developed by Logan Wright for Swift 2.0 here:

/*
 Fun with NSNumber to integer and unsigned integer conversions! This
 bit someone trying to use key-value coding to get the average of a
 given number out of an array of items with an NSUInteger property.

 The NSNumber which came out of the @avg.value KVC method was of value
 588.33333333333333333333333333333333333. The person then tried to access
 this value by calling both average.integerValue and
 average.unsignedIntegerValue.
