public interface TemplateHashModel
extends TemplateModel
```
"hash" template language data type: an object that contains other objects accessible through string keys (sub-variable names). It, in itself, doesn't support listing the keys or values (TemplateHashModelEx does).
In templates they are used like myHash.myKey or myHash[myDynamicKey].
