geoscript.style.ContrastEnhancement

A ContrastEnhancement is a Symbolizer used to style Rasters by modifying the contrast.
You can create a ContrastEnhancement using the normalize method:
```
 def c = new ContrastEnhancement("normalize")
 
```
Or you can create a ContrastEnhancement using the normalize histogram method and a gamma value:
```
 def c = new ContrastEnhancement("histogram", 0.5)
 
```
