turn arm32 assembler instructions into binary machine-code

Prerequisistes

---

You need to have the [arm-eabi-toolchain installed](http://blog.y3xz.com/blog/2012/10/07/setting-up-an-arm-eabi-toolchain-on-mac-os-x)

Usage

---

``` javascript

var through = require('through');

var test = require('tape');

var asm = require('.');

test('should assemble single instruction when given a string', function(t) {

    t.plan(4);

    asm('MOVEQ r0, r1, LSL r2', function(err, i) {

        t.equal(err, null);

        t.equal(i.toString(16), '1a00211');

    });

    asm('MOV r0, r1, LSL r2', function(err, i) {

        t.equal(err, null);

        t.equal(i.toString(16), 'e1a00211');

    });

});

test('should return stream when given a stream', function(t) {

    var tr = through();

    var out = asm(tr);

    var i = 0;

    t.plan(3);

    out.on('data', function(data) {

        if (i===0) {

            t.equal(data.toString(16), '1a00211');

            i++;

        } else {

            t.equal(data.toString(16), 'e1a00211');

            i++;

        }

    }).on('end', function() {

        t.equal(i,2);

    });

    tr.write('MOVEQ r0, r1, LSL r2');

    tr.write('MOV r0, r1, LSL r2');

    tr.end();

});

```
