ProcessVariable (Camunda Platform Javadocs 7.19.0-SNAPSHOT)

```
@Qualifier
@Retention(RUNTIME)
@Documented
public @interface ProcessVariable
```
Annotation for qualifying injection points such that process variables are injected. Requires a process instance to be managed
- @Inject @ProcessVariable Object accountNumber
- @Inject @ProcessVariable("accountNumber") Object account
In both cases, the process variable with the name 'accountNumber' is injected. NOTE: injection points must be of type 'object'.
Can also be used to declare bean-properties to hold process variables in combination with the StartProcess annotation:
```
 @ProcessVariable 
 String accountNumber;  // will be added as a process 
                        // variable to the 'billingProcess'
 
 @StartProcess("billingProcess")
 public void startBillingProcess() {
  ...
 } 
 
```
