Objective: Create a Karel J Robot program which sorts piles of beepers!
Use the code below as a starting point.
Below is an example of sort world before sorting.
Below is an example of sort world after sorting.
/**
* <<< This code is NOT complete >>>
* SortBot should move two robots back and forth along a row
* and sort piles of beepers.
*
* Complete the methods below to make the robots sort!
