// Configuration ----------------------------------------------------------
// Define your list of sites you want HoverZoomMinus to run with,
// 1st array value - 1 will default it to turn on, 0 defaults it to turn off
// 2nd array value - "center" to always spawn it in center otherwise '' [blank] spawns near the mouse
// 3rd array value - allowed interval between respawing of popup. ie when exited on popup but imedietly touches an img container thus making it blinks or unsuable
