##Example - Enable Debug Mode
It is not always feasible to know why a a fail-able initializer may have failed to parse a response. USMapperKit provides the ability to use a build-time flag to print out failures to the console.
To enable Debug mode, add the -DUS2MAPPER_DEBUG flag to the Other Swift Flags in your build settings.

The resulting output in the console will resemble the following:
Business instance could not be parsed, missing values for the following non-optional properties:
- business_uuid
Response:
[response: {
"business_name" : "UsTwoRestaurant";
"business_ratings" : [ 5, 4, 5, 4 ];
"business_open" : 1;
}]
