示例1: stringToDatatype
/**
* Transform a string representing a QTI valueType value in a
* the correct datatype.
*
* @param string $string The QTI valueType value as a string.
* @param integer $baseType The QTI baseType that defines the datatype of $string.
* @return mixed A converted object/primitive type.
* @throws \InvalidArgumentException If $baseType is not a value from the BaseType enumeration.
* @throws \UnexpectedValueException If $string cannot be transformed in a Value expression with the given $baseType.
