This CL updates the TimelineOverviewCalculator by moving it into its own file, and changing its types from `number` to the `MilliSeconds` type. This is important because the trace engine works primarily in microseconds, so if we just use the `number` type we could easily get into a confusing world where we are passing round numbers in different units.
