VariableValues (rxmicro-data-sql 0.4 API)

```
@Documented
@Retention(SOURCE)
@Target({TYPE,METHOD})
public @interface VariableValues
```
Denotes a storage with the values of the predefined variables.

To determine the value of the predefined variable used in the query specified for the repository method, the RxMicro framework uses the following algorithm:
1. If the repository method returns or accepts the entity model as a parameter, the entity model class is used to define the variable value.
2. Otherwise, the RxMicro framework analyzes the optional entityClass parameter defined in the Select, Insert, Update and Delete annotations.
3. If the optional entityClass parameter is set, the class specified in this parameter is used to define the variable value.
4. If the optional entityClass parameter is missing, the RxMicro framework tries to extract the variable value from the VariableValues annotation, which annotates this repository method.
5. If the repository method is not annotated with the VariableValues annotation or the VariableValues annotation does not contain the value of a predefined variable, then the RxMicro framework tries to extract the value of this variable from the VariableValues annotation, which annotates the repository interface.
6. If the variable value is undefined in all specified places, then the RxMicro framework notifies the developer about the error.
