     The default construct is used to give the value of an unspecified
     property.
 
     Generally, this default constructor is called when an unspecified property
     name is specified in operator [] of std::unordered_map that holds the
     Property class.
 
     The default constructed property has an empty "value".
     The implicit cast operator of the Property class constructs the target
     type by default constructor if the string "value" is empty.
 
     Keep in mind that the C++ bool type has a value 'false' when it is
     initialized by default construction.
