AbdealiJK 52b9867be5 Add docs fro update_seq (#1735) 
* Fix typos and messages in docs

* parameter.md: Add docs for updater_seq

Mention the updater_seq parameter which sets the order of the tree
updaters to run and also specifies which ones to run. This can be
useful when pruning is not required or even a custom plugin is
being built along with xgboost.

David Lichtenberg 8156b71912 Typo is OSX installation instructions (#1718) 
The `cd ..;` in the one liner takes you up a directory instead of into the xgboost directory. This will cause that step of the installation to fail. It seems like you are meant to enter the xgboost directory as you did in the instructions for installing xgboost without openmp.

Bargava 62e5b6b8b3 updating Mac installation instructions (#1443) 
In Mac, even after gcc is installed from homebrew, gcc and g++ still point to clang's version. 

Need to update the make/config.mk file to point the gcc and g++ compliers to the version installed by homebrew.
