Remarks

Expected signatures for getter and setter:

// should return true and value of property, if property value found in storage
// should return false if property value not found in storage
static object Getter(Entity object, string propertyName, object defaultValue);
// or
object this.Getter(string propertyName, object defaultValue);
// where defaultValue is default value for property type for current MappingSchema

static void Setter(Entity object, string propertyName, object value)
or
void this.Setter(string propertyName, object value)
