Variables for a Strictly Positive-Definite Correlation Function.
This reflects the `spdcf` definition of the
NGA_gpm_local glTF extension.
Instances of this type are stored as the parameters within a
`CorrelationGroup`.
Parameters (A, alpha, beta, T) describe the correlation decrease
between points as a function of delta time:
```
spdcf(delta_t) = A_t * (alpha_t + ((1 - alpha_t)(1 + beta_t)) / (beta_t + e^(delta_t/T_t)))
```
