* This function splits the two versions on &quot;.&quot; and performs a

* lexical comparison would consider "0.20" to precede "0.3". This method of
* comparison is similar to the method used by package versioning systems like
* deb and RPM.
*
* Version components are compared numerically whenever possible, however a
* version component can contain non-numeric characters. When a non-numeric
* group of characters is found in a version component, this group is compared
* with the similarly-indexed group in the other version component. If the
* other group is numeric, then the numeric group is considered to precede the
* non-numeric group. If both groups are non-numeric, then a lexical
* comparison is performed.
*
* If two versions have a different number of components, then only the lower
* number of components are compared. If those components are identical
* between the two versions, then the version with fewer components is
* considered to precede the version with more components.
