- New output format that's easier to read, while maintaining the stuff Xcode needs for its integration
- Report pending specs in the output, and support Cedar's PENDING macro.
Added PENDING macro for compatibility with Cedar-style pending specs.
Spec examples can now be focused using fit(), or fdescribe() instead of it() or describe(). When specs are focused, all unfocused specs are skipped.
updated readme
PENDING is defined only when SPT_CEDAR_SYNTAX is defined
