ColorSLDMapFunction
```
public class AbstractSLDMapFunction<T>
extends AbstractSLDFunction<T>
```
Abstract implementation of a function which maps integer values to specific other values (colours / densities / etc, parameterised by T). It's primary use is to render categorical data where a single integer maps to a data type. However the <se:Categorize> was already taken and applies to data which falls between thresholds, so this is called <resc:Map> This is adapted from AbstractSLDCategorizeFunction because it is very similar.
