branch: master
commit 6b513978f573e8381cf88d57c9c77bee3087907b

    Added -j8 to make examples in book
    
    Compilation time can be greatly reduced if people use the `-j' option for
    `make', which will distribute the `j'obs into multiple threads. So to help
    the book readers, a `-j8' was added to the example scripts for all the
    libraries and also in Quick start. A comment is added afterwards,
    explaining that the `8' can be replaced with the number of CPU threads.
    
    It could have been `-jN', but that would be a little cryptic and not work
    if people didn't pay attention to the comment, making things a little
    confusing. In this manner, even if they don't have 8 CPU threads, there
    won't be any error and the speed will be up anyway (to the limit available
    by their CPUs).
