ValueObject *	m_parent = nullptr
	The parent value object, or nullptr if this has no parent.

ValueObject *	m_root = nullptr

	Stores both the stop id and the full context at which this value was last updated.

ConstString	m_name
	The name of this object.

DataExtractor	m_data
	A data extractor that can be used to extract the value.

Value	m_value

Status	m_error
	An error object that can describe any errors that occur when updating values.

std::string	m_value_str
	Cached value string that will get cleared if/when the value is updated.

std::string	m_old_value_str
