repaired links to now dead scalamacros.org;

the website `scalamacros.org` is no longer being used for what it was
originally intended for when this documentation was written, so I have
linked to the github repository which contains the original data.

It may be worth it to look into `archive.org` for this purpose, if it is
felt that the repository used is not sufficient.
In the event the repository disapears, I have
created a fork, and plan use it for archival purposes. This fork is
welcome to use by the scala project in such an event.

 Macros are also popular in the community and have already given rise to a number of interesting applications.

 covering the state of the art of macrology in Scala 2.10 from a more academic point of view.
 In the paper we show how the rich syntax and static types of Scala synergize with macros and
 explore how macros enable new and unique ways to use pre-existing language features.
