/**
* Program elements annotated @Removal track the earliest final release
* when a deprecated feature will be removed. This is an internal decoration:
* a feature may be removed in a release earlier or later than the release
* number specified by this annotation.
*
* The POI project policy is to deprecate an element for 2 final releases
* before removing. This annotation exists to make it easier to follow up on the
* second step of the two-step deprecate and remove process.
*
* A deprecated feature may be removed in nightly and beta releases prior
* to the final release for which it is eligible, but may be removed later for
* various reasons. If it is known in advance that the feature will not be
* removed in the n+2 release, a later version should be specified by this
* annotation. The annotation version number should not include beta
*
* For example, a feature with a @deprecated POI 3.15 beta 3
* is deprecated in POI 3.15 and 3.16 and becomes eligible for deletion during
* the POI 3.17 release series, and may be deleted immediately after POI 3.16 is
* released. This would be annotated @Removal(version="3.17")
.
*
* @since POI-3.15 beta 3

* not been removed yet, the version number should adhere to the following format:
* Format: "(?\d+)\.(?\d+)"
* Example: "3.15"
