buttons =======
This option was removed in 1.3 in favor of [header](../display/header) and [buttonText](../text/buttonText).
Defines the buttons and button-text at the top of the calendar.
Boolean/Object, *default*: `true`
`true` will display a previous-month, next-month, and "today" button. The "today" button will only be visible for months other than the current. `false` will display absolutely no buttons. An object hash can be provided to display only *certain* buttons. The hash can have the following properties: { today: bool/string, prevYear: bool/string, prevMonth: bool/string, nextMonth: bool/string, nextYear: bool/string } A value of `false` will not display the button. A value of `true` will display the button with some default text. A string value will display the button *and* customize its text.
