Python rewrite

[joshmoore]

Sorry, I couldn't resist. Don't worry about saying "thanks, but no thanks"; I won't mind. If you're interested, here's what I did:

• Modified the syntax to python (i.e. minimze git diff --word-diff) with all tests passing
• Change to a full pythonized version with all tests passing
• Added full float support (Floats #28); this changed the sparkles slightly
• Added support for negatives

This all is about an order of magnitude faster:

/tmp/spark $ time ./spark -- '0,10,100,1,10,1,10,20,10,40,50,30,10,30,50,60,40,20,304,50,40,50,50'
▁▁▃▁▁▁▁▁▁▂▂▁▁▁▂▂▂▁█▂▂▂▂

real    0m0.023s
user    0m0.013s
sys 0m0.010s
/tmp/spark $ time ./spark.sh -- '0,10,100,1,10,1,10,20,10,40,50,30,10,30,50,60,40,20,304,50,40,50,50'
▁▁▁▃▁▁▁▁▁▁▂▂▁▁▁▂▂▂▁█▂▂▂▂

real    0m0.290s
user    0m0.092s
sys 0m0.229s

If this is something that anyone wants to consider, my next step would be to remove print_tick loop, since with float support we can compute the tick directly.

But now I should get back to real work. :)

Cool.
