Allows casting to a bool to check if the field has a value without directly calling has().

This can be used as in the following (assuming 'parent' is a parent message, and this field is called 'myField')

Command::StringField& f = parent.myField();
if (f)
  std::cout << "Field has value: " << f.get() << std::endl;
else
  std::cout << "Field has no value!" << std::endl;

void hebi::Command::StringField::set

(

const std::string &

value

)

Sets the field to a given value.
