updated examples in README.md and removed inline from agenda.pxd. 

The code compiled beautifully on OSX Mavericks 10.9.2, using the Python and Cython from Anaconda 1.9.1. One small change was necessary, in agenda.pxd the inline modifier on nsmallest had to be removed. The corresponding one in agenda.pyx was retained. 

In addition, the examples given in README.md were updated. The original command line for the third example was missing a parameter for --rerank, so I added 3.
