/**
 * Week 3 - A Larger Example (String, Array, RegExp):
 *
 * Write a series of functions to accomplish the following, building a larger program as you go:
 *
 * 1. Split the string into an `Array` of separate rows (i.e., an `Array` with rows separated by `\n`).
 *    Bonus: how could we deal with data that includes both Unix (`\n`) and Windows (`\r\n`) line endings?
 *
 * 2. Each row contains information user info: `ID`, `Name`, `Phone Number`, and `Height` info all separated by commas.
 *    Split each row into an `Array` with all of its different fields.  You need to deal with extra and/or no
