/* Turn an input field into an entry point for a time value.
|
|
The time can be entered via directly typing the value,

via the arrow keys, or via spinner buttons.
|
|
It is configurable to show 12 or 24-hour time, to show or hide seconds,
|
|
to enforce a minimum and/or maximum time, to change the spinner image,
|
|
and to constrain the time to steps, e.g. only on the quarter hours.
|
|
Attach it with $('input selector').timeEntry(); for default settings,
|
|
or configure it with options like:
|
|
$('input selector').timeEntry(
|
|
{spinnerImage: 'spinnerSquare.png', spinnerSize: [20, 20, 0]}); */
