Some functions to handle assembler

Nice! If this were a module, you could do something like this from within an existing module, and it would all 'just work':

var tst1 = require("asm").load("int(int,int)",[0x18­40,0x4770]);

The module could also do some more interesting stuff - perhaps using STM32F1Flash to write the data into flash memory, so it can still be used after power off.
