class_docstr: Basic Hello World that displays Hello <name> in MATLAB
  
  Returns
  -------
  
  matlab_output : capture of matlab output which may be
                  parsed by user to get computation results
  
  Examples
  --------
  
  >>> hello = HelloWorld()
  >>> hello.inputs.name = 'hello_world'
  >>> out = hello.run()
  >>> print out.outputs.matlab_output
code: def run(self, **inputs):
      # Inject your script
      self.inputs.script = self._my_script()
      results = super(MatlabCommand, self).run(**inputs)
      stdout = results.runtime.stdout
      # Attach stdout to outputs to access matlab results
      results.outputs.matlab_output = stdout
      return results
