BSON-v0.999.3-TRIAL - BSON serialization and deserialization

Changes for version v0.999.3 - 2016-06-23 (TRIAL RELEASE)

Bug fixes
- Fixed detection of Infinity/NaN during serialization of BSON::Double to JSON for Windows perls before 5.22.0.
- Work around compilation ambiguities involving the core keyword 'ref' and the BSON::DBRef attribute 'ref' in certain versions of Moo.
Testing
- Require newer Path::Tiny with full-featured "basename" method.

Changes for version v0.999.2 - 2016-06-13 (TRIAL RELEASE)

Added
- Added full "minimum set" of overloaded operations to numeric and string type wrappers.
- Added convenience functions to provide "Infinity" and "NaN" double values.
Testing
- Replace double test cases for better portability.
- Skip threads tests before 5.8.5 because of problems with weak references during global destruction.

Changes for version v0.999.1 - 2016-06-08 (TRIAL RELEASE)

Testing
- Checks for JSON serialization of doubles with no fractional part with a regular expression to account for the way that different JSON backends will handle it.
- Skip testing TO_JSON under JSON::PP if the value to be converted is false. See https://github.com/makamaka/JSON-PP/pull/23 for why.
- Skip some BSON double tests on 32-bit perls with JSON::PP to work around a JSON::PP bug.
~Internal Changes~
- Disambiguates calls to 'ref' in BSON::DBRef to avoid warnings.

Changes for version v0.999.0 - 2016-06-01 (TRIAL RELEASE)

!!! Incompatible Changes !!!
- Internal representation of BSON::Bool changed to make it a subclass of boolean.pm for conistency with other "boolean" type classes on CPAN.
- All BSON type wrapper classes are now immutable; accessors have been changed to read-only.
*** Deprecations ***
- BSON::Binary deprecated in favor of the new BSON::Bytes module.
- BSON::Bool deprecated in favor of direct use of boolean.pm.
- BSON::ObjectID deprecated in favor of the new BSON::OID module.
- The 'ixhash' option is deprecated in favor of 'ordered' and the resulting tied object is no longer guaranteed to be Tie::IxHash. This will allow future optimization, as Tie::IxHash is extremely slow.
API
- BSON module is now object-oriented, with an API and options directly compatible with the MongoDB driver. Options set as constructor attributes apply to all encoding/decoding, unless options given to methods override them.
- Added a method for inflation of MongoDB's extended JSON format to BSON type wrapper objects.
BSON types
- Added new type wrappers to cover all BSON Types, including forthcoming Decimal128.
- Rationalized/harmonized BSON type classes for compatibility with pre-existing MongoDB BSON classes. Classes that could not be made to interoperate are deprecated as listed above.
Bug fixes
- Fixed numerous encoding and decoding bugs revealed by greater test coverage (e.g. fixes to UTF-8 encoding/decoding).
Testing
- Significantly improved test coverage, including tests using a standardized BSON corpus.
~Internal Changes~
- Pure-perl implementation split into a separate module to avoid its load time in the future when an XS implementation becomes available.
- Will prefer BSON::XS (when released) or fallback to BSON::PP; PERL_BSON_BACKEND environment variable will override.
