Injector (Charba - J2CL and GWT charts library based on CHART.JS)

java.lang.Object
- org.pepstock.charba.client.Injector

```
public final class Injector
extends Object
```
This utility injects ChartJS java script and CHARBA custom java script implementation (for some utilities) in the web page of application, in the HEAD.
It enables also to inject other script in the web page, necessary when you want to use some Chart.JS extensions.
It tracks the resources which have been injected using as key their name and class name to avoid that however will inject own resources will use the same name of already injected resources.
