Side
Sides render a side that if used with other sides generates a regular polygon figure.  By default, up to 60 sides can be placed in an orbit.
Look and feel
Sides can be customized by adding CSS border and background properties.
Adjusting radial layout
Arbitrary side angle.
.angle-*: Set starting point angle from 0 to 360 degrees, overrriding automatic radial arragement.
Relative side orbital position
By default, .side is positioned in the middle of orbit path. To change that, there some CSS utilities:
.inner-orbit: To place an.side just below its orbit.
.outer-orbit: To place .side just above its orbit.
