##Usage Utility code used across sussol repositories, in four different categories

Authentication

Re-exports the three methods from authentication-utilities

Scheduling

Provides the ability to schedule functions after an interval, and maintains handles on any scheduled functions so they can be canceled An instance of Scheduler provides two methods:

schedule(callback, interval) - Schedules the callback function to be executed after interval milliseconds
clearAll() - Cancels any scheduled functions that have not been executed. Should be called for safety before the Scheduler instance goes out of scope

import { Scheduler } from 'sussol-utilities';

function exampleScheduling() {
  const permanentScheduler = new Scheduler();
  const temporaryScheduler = new Scheduler();
  temporaryScheduler.schedule(() => {console.log('Welcome')}, 0);  // Say 'Welcome' immediately but asynchronously
  permanentScheduler.schedule(() => {console.log('Hello')}, 1000); // Say 'Hello' after 1000 milliseconds
  temporaryScheduler.schedule(() => {console.log('World')}, 2500); // Say 'World' after 2500 milliseconds
  temporaryScheduler.clearAll();
}

Formatting

Exports four methods for formatting strings

formatDate(date, format) - Returns the date object passed in as a string in either the format dd/mm/yyyy or dd.mm.yyyy depending on whether 'slashes' or 'dots' is passed in as the format argument (defaults to slashes), or any formatting accepted by moment
formatDateAndTime(date, format) - As above, but with the time appended to the end in the format defined by the locale
truncateString(string, maxLength) - Returns the string chopped off at maxLength, with ... replacing the last three characters if it overflowed
formatPlural(singular, plural, count) - Returns either the singular or plural version of the string, depending on the number passed in count
