Added a palindrome module to the playground.

[tacosontitan]

TL;DR

This PR adds support for new iterators, logical functions, and a dedicated module for solving the palindrome problem. This problem can be solved with a minimum of 6 + n bytes where n is the length of the input variable or literal:

Pal(121);

Reverse

This PR adds support for a generic reversal method that takes an input T, converts it to a string and then reverses the character sequence:

var testValue = "abc";
var reversedValue = Rev(testValue);
Console.WriteLine(reversedValue);

The output of the snippet above is:

cba

Equals Reversal

This PR also adds support for a method which invokes the aforementioned reversal and determines if the pre-reversed input is equal to the reversed output:

var testValue = 121;
var equalsReversal = testValue.EqRev();
Console.WriteLine(equalsReversal);

The output of the snippet above is:

true
