Rather than producing separate files for each module, the default build now
produces a single file. This should encourage better page-load performance as
the files were relatively small. Also, it's easier to deal with only one file
rather than many, especially if you're not quite sure what the dependencies are.
You may still create minimized builds, if you don't want every feature.
This commit also demotes the chart components to the examples directory, rather
than keeping them as part of the core library. As always, D3 is not a charting
library, and these were ever only intended to serve as examples.
The greatArc class is the new name for greatCircle, which actually represents
great arcs. Meanwhile, a new greatCircle class is for great circles. The new
greatCircle class replaces the old clip class, providing clipping and resampling
functionality (using greatArc internally). This isn't backwards-compatible, but
I may forgo the major version number bump in light of the fact that greatCircle
was just added, and not used in any (official) examples or documented.
