* Build an array of at minimum a specified length from an existing array and a padding value. IF the array is already larger than the target length, it will not be shortened.
 * @param {Array} anArray - the source array to copy into the result.
 * @param {*} padding - the value to add to the new array to reach the desired length.
 * @param {Number} targetLength - The desired length of the return array.
 * @returns {Array} an array of at least 'targetLength' length
