0.1.0-alpha.2

• get() methods on svg attributes can no longer by called in Kotlin.
  • Previously they could throw. This should make it so that cannot happen if someone does this by mistake.
• Made Url(...)'s constructor public and added a convenience url(...) function to call the constructor as this
  matches SVG's url call quite well.
• Added convenience method to repeatDur so repeatDur can be called with a Duration (ex repeatDur(10.seconds))
• Added convenience method to dur so dur can be called with a Duration (ex dur(10.seconds))
• DelayedTagConsumer will now throw if you attempt to set elements after starting a child element.
  • This mirrors the behavior of kotlinx-html but I'll be honest that I don't like it.
  • Prior to this change attributes would simply disappear if they were after a child element.
  • This affects svgString { ... } and any Appendable SVG builder.
  • This does not affect DOM based builders
