Fix: Sonatype Nexus publishing

There seems to be a problem with `group` and `version` set on the root project conflicting with the same set on the subprojects when trying to use the Nexus publishing plugin: gradle-nexus/publish-plugin#150

These changes resolve this by aligning all of them. Once this needs to deviate we may have to revisit.

 This library includes a generic base class `Interval<T, TSize>` which can be used to create intervals for any type.
 To achieve this, it directs type operations to `IntervalTypeOperations` which the constructor takes as a parameter.
