Detailed Description

Helper class to perform computations that require both Tempo and Meter at a given point in time.

It may seem nicer to make this IS-A TempoPoint and IS-A MeterPoint. Doing so runs into multiple inheritance of Point, plus the major semantic issue that pairing a tempo and a meter does in fact allow for two positions, not one. That means we have to provide accessors to the TempoPoint and MeterPoint and thus it may as well be HAS-A rather than IS-A.

This object should always be short lived. It holds references to a TempoPoint and a MeterPoint that are not lifetime-managed. It's just a convenience object, in essence, to avoid having to replicate the computation code that requires both tempo and meter information every place it is used.
