# Remote select implementation
#
# options
#
#    selector - css selector for selects
#
#    custom callbacks:
#    beforeSend(RemoteSelect, select)
#    success(RemoteSelect, select
#    complete(RemoteSelect, select)
#
#    spinnerParentSelector - where should search for .spinner
#
# this will run within a closure wrapper, so, to expose it as a global variable, we attach it to the window object
