Update compiler description (now a working Scheme program).
...
Maps lexical variables, decodes argument lists, and flattens procedures
to simple lists of primitive operations, but does not yet convert to
CPS or perform register (gN, iN, fN) allocation, much less optimization.

Add bytecodes to skip the rest of a block based on a condition.
...
Should simplify error-handling and sequences of primitive tests.
Also, automatically instantiate templates used in the tail-call lambda & cont'n fields.

Swap continuation & context in the lambda and template structures.
...
This is to separate the three 'call' parameters (target, argv, ctx) from
the 'return to' parameter (k). The old order made it look as if the dynamic
context was in some way related to the continuation, which is not the case.

Add a reserved input code for 'self', the current lambda.
...
Correct an error in the documentation for the condition bytecode(s).
Adjust the printer to limit the depth of non-cyclic object output.

Check in a second program, this time demonstrating basic I/O.
...
Also filter cycles and long byte-strings from print_value() output.
Added three new bytecodes to get the sizes of vectors, strings, and structs.

Adjust number-reader to allow 'negative zero' FP values.
...
Also add builtins for NaN and +/- infinity, and bytecodes for classification.

Implement the remaining bytecodes. Adjust some of the numbering.
...
Also, use #<undefined> for "not yet initialized" and #f for "no value".

Added built-in structure types and interpreter core (w/o bytecode).
...
Improved timing resolution by using clock_gettime() instead of clock().
Also gave project a name: Rosella. Play on 'Parrot' (Perl 6 VM).
