New in SVN:
-----------
* Value
- Updated the Value::isFoo methods to work as follows:
* isInt, isInt64, isUInt, and isUInt64 return true if and only if the
value can be exactly representable as that type. In particular, a value
constructed with a double like 17.0 will now return true for all of
these methods.
* isDouble and isFloat now return true for all numeric values, since all
numeric values can be converted to a double or float without
truncation. Note that the conversion may not be exact -- for example,
doubles cannot exactly represent integers above 2^53.
* isBool, isNull, isString, isArray, and isObject now return true if and
only if the value is of that type.
New in JsonCpp 0.6.0:
