WIP - arcs implemented, but won't animate. Need to work on tweens?
Animations sort of work.
Selections now persist throughout transitions. Need to display text.

Transitions are still buggy, but will go with them for the time being.

Merge branch 'arc' of https://github.com/cmdoptesc/2013-06-d3-exploration into arc

Conflicts:
	nextbus-d3.js
Refactored code.
Now displays multiple bus lines. Takes fastest 6 buses.
Implemented old deletion algorithm to get rid of buses that have departed.
Multiple now aggregated to a single query every 14 seconds by using
Nextbus' predictionsForMultiRoutes command.
Added delete query option.

Also, previous commit included refactoring of bus deletion (for buses
that have departed), and fix of the chart.timer (typo with chart.time).
WIP - displays time of selected arc on SVG.

However, have issue with the revert action ("unclicking" a selection).
Somehow, a closure is being created with the .on('click') handler and
it is referencing dataset from the first initialization.
Fixed "unclick" issue by moving event handler away from enter().
Rewrote toMin function to round up/down depending on how many minutes
there are.
Refactored code. Changed color scheme.
Beginnings of Bootstrap styling.

Selections now display buses.
Finally took *out* multiple charts feature.

More bootstrappin'.
Renamed variables. Last commit before major cleanup for code review.
Minor clean up for code review.
Wrote brief readme.
