Do not directly call fiber-based funcs when ncpu is 1. It causes segmentation fault.

Fix segmentation fault when ncpu is set to 1
Resolved issue in likelihood calculation for LDA.  Note that likelihood calculation is relatively slow (costly) and probably should not be enabled by default.
To accelerate likelihood calculations I have added code to precompute the loggamma for a range of common values.

Fix minor typo in basic GraphLab tutorial. Thanks Fernando for your fix!
Put quotes around generator in configure script
Add skeleton partial-results app
Add pagerank with feature calculation.

- derivatives as features
- load final page rank to compute accuracy
- page rank RMSE and ranking comparison as accuracy metrics
Fix rank calculation and make max vertices a command line option.
Present rank error better

- fix typo: "rank mse" instead of "rank rmse"
