Added TypeMapper abstraction to allow plugging in a custom implementation. Current type handling logic is now in DefaultTypeMapper which additionally allows customizing the key the type information its stored under or disabling writing type info by setting the key to null.
Added ConfigurableTypeMapper implementation that gets a Map configured to define Strings to be used to store type information.
Really only use the custom target type in case it is a real subtype of the basic one. Before that we used the plain custom one which was is lacking generics information potentially available in the basic one.
In case a repository query method returns a domain type not assignable to the repository domain type we have to use the repositories domain type to determine the collection but still use the returned domain type to hand to the unmarshalling. Thus, we need to set up a custom MongoEntityInformation to reflect this scenario.
Extended MappingMongoEntityInformation to allow manually defining a custom collection name. EntityInformationCreator was extended accordingly and MongoQueryMethod now sets up the EntityInformation accordingly.
Extracted readCollectionOrArray(…) method and make sure it's used everywhere a Collection has to be read. Test cases now checks that empty collections are correctly read when using @PersistenceConstructor as well.
Use QueryMethod accessor methods instead of dropped Type enum to determine query execution. Added custom MongoParameters and MongoParameter to allow discovering a Distance parameter for repository queries which will transparently add a 'maxDistance' clause for *Near criterias in query methods. If the given Distance is equipped with a Metric we will rather use $nearSphere over $near.
Added asList() to Point class to circumvent bug in BasicBSONObject.equals(…) which breaks equals(…) comparisons of DBObjects in case they use arrays as values. See [0] for details. Adapted usage of Point objects to use asList() over asArray().

Introduced GeoResult value object as well as NearQuery. NearQuery allows definition of an origin and distances. Introduced a Metric interface and Metrics enum to carry commonly used metrics like kilometers and miles to ease the handling in NearQueries. Introduced Distance value object to capture distances in Metrics.
Added some defaulting code in MappingMongoConverter that converts DBObject instances into Maps in case the raw property type is Object (see getMoreConcreteTargetType()).
Replaced manual ID conversion with delegating to QueryMapper. Added ObjectId as Mongo native type to CustomConversions and added unit tests around its handling.
Map values are now handled correctly regardless of the actual Map value type declaration (can be Object in the most open case). We now handle collections as Map value types correctly. BasicDBList instances are now hinted to become Lists by default (if not typed to another collection type by the property).
Reduced visibility of MappingMongoConverter.addCustomTypeKeyIfNecessary(…) and made createCollectionDBObject(…) safe against null values for the TypeInformation.
BasicQuery accidentally shadowed limit and skip fields of Query and introduced setters instead of builder style mutators. This caused the getters not returning the values set throughout the mutators which essentially turned off pagination for manually defined queries.
Removed the shadowing and created test case. Refactored constructors.
Removed quite some obsolete methods from MongoConverter interface. Renamed maybeConvertObject(…) to convertToMongoType(…). Moved implementation of that method into MappingMongoConverter. Let the implementation transparently use custom Converters as well. Removed SimpleMongoConverter. Switched QueryMapper implementation from using a MongoConverter to use a ConversionService. Removed custom "maybe convert" logic from ConvertingParameterAccessor in favor of MongoWriter.convertToMongo(…).
Added converter to handle BigInteger values. Adapted id handling to try converting and object to String before taking the id as is. Made custom converter implementations safe against invocations with null.
