 * This function calculates the initials/acronym for a given name.

 * It will pass back the characters with the same casing as the original string

 *
 * @param {string} name The full name of the item to turn into initials
 * @param {number} initialsLength (Optional) How many characters to show (max 2 allowed)
 * @param {string} initials (Optional) Custom initials (max 2 characters)
