HelpersBuilder (trimou-core 2.3.0.Final API)

java.lang.Object
- org.trimou.handlebars.HelpersBuilder

```
public final class HelpersBuilder
extends Object
```
A simple builder for helpers map. It's useful when registering built-in/basic helpers with sensible default names (each, if, etc.) - no need to explicitly declare a helper name.
```
 HelpersBuilder.empty().addSet().addIsEven().add("myHelperName", new MyHelper())
         .build();
 
```
