 * Setting the header options to false will display no header.
 * An object can be supplied with properties left, center, and right.
 * These properties contain strings with comma/space separated values.
 * Values separated by a comma will be displayed adjacently.
 * Values separated by a space will be displayed with a small gap in between.
 * Strings can contain any of the following values:
 * <code>
 * {
 * left:   'title',
 * center: '',
 * right:  'today prev,next'
 * }
