Renaming test/unit-tests to test/cg-tests to prepare for adding another suite of tests.
Added instrumentation of property reads to determine which properties are available on the base expression.
Added ToObject conversion for handling reads on non-object bases.
Don't list numeric properties; they are not interesting for our purposes.
Small fix to test runner.
Adapted property read recording to new instrumentation.
Merge pull request #3 from ecspat/property-reads
