NodeMap (d4cdmshared 4.6.7-SNAPSHOT API)

```
public class NodeMap
extends java.lang.Object
```
Provide a bi-directional 1-1 map between DapNode instances and CDMNode instances. There is a complication. Currently, the hashCode() in ucar.nc2.Variable (and other classes) is unstable when objects are being incrementally constructed. So until and unless that is changed, it is necessary to provide a way to map CDMNode <-> DapNode that is independent of e.g Variable.hashCode(); We do this by overriding hashCode() to use Object.hashCode() explicitly.
