This function takes a wider-spaced storm track (e.g., every 6 hours) and interpolates to every 15 minutes. To do this, it uses natural cubic spline interpolation using the `spline` function from the `stats` package. The track is only interpolated if there are three or more observations on the central location of the storm (this is almost always the case for storms tracked in the HURDAT2 dataset).
