[Axiom-developer] compiler.boot issue #370 patch

[daly]

Stephen,

I pushed the compiler.boot patch.

I also re-engineered the testing machinery so the unit test spad code
you wrote is included in the input test file. This unit test code is
now run during build time and then the regression machinery tests the
result. This is general purpose and we can write spad code in input 
files for unit testing, somewhat like the AldorUnit idea.
