  Creates and returns a new attribute mapping specifying that data is to be read from a given key path on a source object

  Attribute mappings define transformation between key paths in the source and destination object beings mapped. In the simplest

  The next most common use-case is the transformation of identical data between two different key paths in the
  source and destination objects. This is typically encountered when you wish to transform inbound data to conform with the naming
- conventions of the platform or the data model of your application. An example of this type of transformation would be from the 
+ conventions of the platform or the data model of your application. An example of this type of transformation would be from the
  source key path of `first_name` to the destination key path of `firstName`. In this transformation, the key paths have diverged
  but both sides of the mapping correspond to NSString properties.
- 
+
  The final type of transformation to be specified via an attribute mapping involves the transformation between types in the mapping.
  By far, the most common example of this use-case is the transformation of a inbound string or numeric property into a date on
  the target object. For example, consider a backend system that returns the creation date of a piece of content in a JSON payload.
  This data might be returned in JSON as `{"created_on": "2012-08-27"}`. In a given application, the developer may wish to model this
- data as an NSDate `createdOn` property on the target object. An attribute mapping to support this mapping would specify a source 
+ data as an NSDate `createdOn` property on the target object. An attribute mapping to support this mapping would specify a source
  key path of `created_on` and a destination key path of `createdOn`. On the destination object, the `createdOn` property would be defined
  as `@property (nonatomic, strong) NSDate *createdOn;`. At mapping time, the mapping operation inspects the type of the content being
- mapped and attempts to transform the source content into the type of the desination property specified by the mapping. In this case,
