 *
 * - modified script dubbed GoDDaMn or gddm.gs (Google Docs Data Marge)
 * - modified script published 
 * - Added String replacement instead of Paragraph replacement
 * - Modified the replacement string TAG format to :key:
 * - the substituted Strings are set in Bold to be 'highlighted' in the output file
 * - changed 'customer' to 'employee' because this is the use we make of it in Inviqa -
 * - if no employee_ID is embedded in the script, then the script sources it from the currently selected line of the spreadsheet
 * - The modified script is meant to be run as an embedded script in a spreadsheet and triggered at any Form submission,
 *   in such case the employee_ID is the I of the newly inserted line, and this is a default behaviour of Google Script
 * 
 * IF the script is run manually, the function to run is 'generateEmployeeDatasheet'
