Ceylon Solar System Example

This little example application demonstrates the use of Ceylon as an alternative to client-side JavaScript. In particular, the example shows:

• a simple, typesafe, object-oriented program,
• dependence on an external [cross-platform math module][xmath] written in Ceylon and hosted on
