// isInteger, for example, will only return true if it is
// passed a string containing an integer; if it is passed
// the empty string, it will return false.
//
// You can change this default behavior globally (for all
// functions which use defaultEmptyOK) by changing the value
// of defaultEmptyOK.
//
// Most of these functions have an optional argument emptyOK
// which allows you to override the default behavior for
// the duration of a function call.

// say "if the user puts anything in this field, it must
// be an integer (or a phone number, or a string, etc.),
// but it's OK to leave the field empty too."
// This is the case for fields which are optional but which
