// Create an array containing the range of integers or characters from low to high (inclusive)

// version: 1109.2015
// discuss at: http://phpjs.org/functions/range
// + original by: Waldo Malqui Silva
// * example 1: range ( 0, 12 );
// * returns 1: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
// * example 2: range( 0, 100, 10 );
// * returns 2: [0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
// * example 3: range( ‘a’, ‘i’ );
// * returns 3: [‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’, ‘g’, ‘h’, ‘i’]
// * example 4: range( ‘c’, ‘a’ );
// * returns 4: [‘c’, ‘b’, ‘a’]
