ApproxCos (glimpse-full-assembly 4.0.0 API)

java.lang.Object
- com.metsci.glimpse.util.math.approx.ApproxCos

```
public class ApproxCos
extends Object
```
Similar to the classes in com.metsci.glimpse.util.math.fast, but uses linear interpolation between samples instead of nearest-neighbor.
Anecdotally, speed is about 12x faster than Math.cos(double). With 100k samples, max error is around 5e-10. Max error decreases as the number of samples increases.
