## Installation

    npm install bubble-boy

## Testing

    npm test

## Using

    var bubbleBoy = require('bubble-boy');

    bubbleBoy("i = 1")
    // sandbox.i = 1

## Implementation Details

    log("hello")
    // sandbox.log("hello")

    console.log("hello")
    // sandbox.console.log("hello")

    i = 10
    // sandbox.i = 10

    i++
    // sandbox.i++

    first.second.third = 10
    // sandbox.first.second.third = 10

    function f(foo) { foo = 10; }
    // foo = 20;

    function f(foo) { foo = 10; }
    // sandbox.foo = 20;

    f = function() {};
    f("test");
    // sandbox.f = function() {};
    // sandbox.f("test");

    function f(foo) { foo = 10; }
    // function f(foo) { foo = 10; }

    function f(foo) {
      function b() {
        foo = 10;
      }
    }
    // function f(foo) {
    //   function b() {
    //     foo = 10;
    //   }
    // }

    function b() {
      f = function() {};
      f("test");
    }
    // function b() {
    //   sandbox.f = function() {};
    //   sandbox.f("test");
    // }

    function f(bar) {
      function localFunc() {}
      localFunc(bar);
    }
    // function f(bar) {
    //   function localFunc() {}
    //   localFunc(bar);
    // }

    function f(bar) { globalFunc(bar); }
    // function f(bar) { sandbox.globalFunc(bar); }

    var f = function() {};
    f("test");
    // sandbox.f = function() {};
    // sandbox.f("test");
