The process.env.TZ trick no longer seems to work. The fix automatically
adds an offset to the minutes being set, relative to the current
timezone. It assumes that the dates being tested in the scope are not in
DST, since the offset is relative to the timezone offset at the epoch.
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.
