Unit Test System and Desktop Mode

[calebh]

Currently the standard library (and the compiler itself) has no unit tests. The standard library is an obvious target since unit tests for these would exercise many parts of the compiler. Either the compiler would have to be able to target desktop environments, or we would need to emulate some Arduino boards.

Perhaps we should consider a Juniper "desktop mode" which generates C++ code for use on x64. This could eventually lead to Juniper finding applications on typical desktops, which we would have to think about carefully.

If this would entail adding support for running tests to the compiler itself, a QuickCheck-style system would be fantastic, though non-trivial to implement, but there's a lot of prior art.
