Release 0.94

Bug fixes

• Incorporates contributions from Cory Fields for silencing some compiler warnings
• Fixes bug reported by Vitaliy Gusev in json object operator[size_t]
• Fixes bug in json is_empty method for empty objects

Changes

• json constructors that take string, double etc. are now declared explicit (assignments and defaults to get and make_array methods have their own implementation and do not depend on implicit constructors.)
• make_multi_array renamed to make_array (old name is still supported)
• Previous versions supported any type values through special methods set_custom_data, add_custom_data, and custom_data. This version introduces a new type json::any that wraps any values and works with the usual accessors set, add and as, so the specialized methods are no longer required.

Enhancements

• json get method with default value now accepts extended types as defaults
• json make_array method with default value now accepts extended types as defaults

New extensions

• Added jsoncons_ext/boost/type_extensions.hpp to collect
  extensions traits for boost types, in particular, for
  boost::gregorian dates.
