Usage:
```
var Layout = require("Layout");
var layout = new Layout( layoutObject, btns )
layout.render(optionalObject);
```
For example:
```
var Layout = require("Layout");
var layout = new Layout( {
type:"v", c: [
{type:"txt", font:"20%", label:"12:00" },
{type:"txt", font:"6x8", label:"The Date" }
]
});
g.clear();
layout.render();
```
layoutObject has:
* A `type` field of:
* `undefined` - blank, can be used for padding
* `"txt"` - a text label, with value `label` and `r` for text rotation
* `"txt"` - a text label, with value `label` and `r` for text rotation. 'font' is required
* `"btn"` - a button, with value `label` and callback `cb`
* `"img"` - an image where the function `src` is called to return an image to draw
* `"custom"` - a custom block where `render(layoutObj)` is called to render
