5c5246fb49 Refactor MKDataModel 
MKDataModel is now a semi-abstract base class instead of a protocol.  This allows extension via category.  Instances of MKDataModel can be chained together via a datasource argument, which enables data models to be composed.

f14dc63f20 Workaround: NSNumber can not store unsigned values 
NSNumber does not store unsigned values *as unsigned*.  When initialized with an unsigned number, NSNumber stores it as signed using the next highest bit-width.

This is a problem for Mach-O Kit’s description system, parts of which expect that the objCType of an NSNumber will exactly correspond to the primitive type that NSNumber was initialized with.

The workaround is to define a custom NSNumber subclass for storing unsigned values.  A new macro `_$()` is added to replace `@()` for boxing primitive numbers.  `_$()` uses the  MK NSNumber subclass where appropriate.

3869aa09cf Add MKComboFormatter 
MKComboFormatter is used to combine a raw value representation and a refined value representation.  This could be used for presenting enumerations, where you want to display the raw (numeric) value and the corresponding element from the enumeration.  For example:

1 (REBASE_TYPE_POINTER)
