  * TEC - Get raw '_EventCost' field without running through is_numeric(), and add currency symbol only if cost begins with a number (and entire cost value is not zero -- but number with leading zero would work)
  * Does NOT have any effect for an event with Tickets from https://wordpress.org/plugins/event-tickets/ (because then cost can vary, like $0-30)
  *
  * From https://gist.github.com/cliffordp/b74ef779f9dbfff291bc2fa4dfebad1e
