/**
*
* Even page footer value. Corresponds to even printed pages.
* Even page(s) in the sheet may not be printed, for example, if the print area is specified to be
* a range such that it falls outside an even page's scope.
* If no even footer is specified, then the odd footer's value is assumed for even page footers.
*
* The even footer is activated by the "Different Even/Odd" Header/Footer property for the sheet.
* If this property is not set, the even footer is ignored, and the odd footer is used instead.
*
* Creating an even header or footer sets this property by default, so all you need to do to
* get an even header or footer to display is to create one. Likewise, if both the even header
* and footer are unset, then this property is unset, and the odd header and footer are used
* for even pages.
