   * This class is used for auto-upgrade purposes.

   * The idea is that instances of this class are put in a sequential order, and that the current version is determined from the ACT_GE_PROPERTY table.
   *
   * Since sometimes in the past, a version is ambiguous (eg. 5.12 => 5.12, 5.12.1, 5.12T) this class act as a wrapper with a smarter matches() method.
