StandardOptions
```

A command line argument receiver.
All non-positional arguments of a Command need a corresponding receiver to accept it through either testOption(String) or testParameter(String). If any receiver rejects a non-positional argument, the CLI will exit with an error.

- Method Detail
  - testOption
```
default boolean testOption(java.lang.String name)
```
    Test if the given value-less option is accepted by the receiver.
    If the option is accepted, the receiver should store a stateful value to indicate the option was received, and the CLI will skip the argument for further processing.
    
    Parameters:
    
    name - Name of the option to test.
    
    Returns:
    
    Returns true if accepted.
  - testParameter
```
default java.util.function.Consumer<java.lang.String> testParameter(java.lang.String name)
```
    Test if the given parameter that requires a value is accepted by the receiver.
    If the parameter is accepted, the receiver returns a Consumer that receives the expected value, and it should store a stateful value to allow the value to be later recalled. The CLI will skip the argument for further processing.
    
    Parameters:
    
    name - Name of the parameter to test.
    
    Returns:
    
    Returns a consumer if accepted or null if rejected.
