 * 7 kyu: Splicing
 *
 * The object of this kata is to create a function called removeValue that removes all of a certain
 * value from an array using .splice() and then returns the array. If the array is empty or has no 
 * element to remove it should return false.
 * 
 * example:
 *
 * arr = [1, 2, 1, '1', 3]
 * arr.removeValue(1); // returns [2, '1', 3]
