/**
 * This function calculates the initials/acronym for a given name.
 * It defaults to only 2 characters and will take the first character (of each word).
 * If only one word is supplied for the name, it will only pass back the first letter of the word,
 * unless forced to 2 letters by setting `initialsLength` to `2`.
 * It will pass back the characters with the same casing as the original string
 * unless otherwise specified.
 *
