    * [new TomatoSauce(config)](#new_TomatoSauce_new)
    * [.run()](#TomatoSauce+run)

<a name="new_TomatoSauce_new"></a>

### new TomatoSauce(config)
The main application for tomato sauce. Listens for connections and serves
random combinations of screens and renderers

The main entry point is the `#run()` function.

It emits a listening event that contains the server information on
the `server` key inside the `data` property of the event.

It also emits an error event that contains the error information on
the `error` key inside the `data` property of the event.


| Param | Type | Description |
| --- | --- | --- |
| config | <code>object</code> | the configuration object used to extend the properties. |

<a name="TomatoSauce+run"></a>

### tomatoSauce.run()
Main entry point, initializes the server and binds events for connections

**Kind**: instance method of [<code>TomatoSauce</code>](#TomatoSauce)  
<a name="Util"></a>

## Util : <code>Object</code>
Module containing utility functions

**Kind**: global variable  

* [Util](#Util) : <code>Object</code>
    * [.parse16BitBuffer(buffer)](#Util.parse16BitBuffer) ⇒ <code>Number</code>
    * [.pickRandom(array)](#Util.pickRandom) ⇒ <code>Any</code>
    * [.loadFiles(path)](#Util.loadFiles) ⇒ <code>Array</code>

<a name="Util.parse16BitBuffer"></a>

### Util.parse16BitBuffer(buffer) ⇒ <code>Number</code>
Parses a 16 bit number buffer

| array | <code>Array</code> | the array to use |

<a name="Util.loadFiles"></a>

### Util.loadFiles(path) ⇒ <code>Array</code>
For a gi ven path, requires all of the files and returns an array
with the results. If the directory contains any non-requireable
files, it will fail.

**Kind**: static method of [<code>Util</code>](#Util)  
**Returns**: <code>Array</code> - the array of all the loaded modules  

| Param | Type | Description |
