### Syntax
myHash.getFromPath(path);
### Arguments
1. path - (*string*) the path to the key for the value you wish to retrieve
### Returns
* (*null* or *mixed*) if the path has no value, *null* is returned; otherwise the value that corresponds to the path is returned.
### Example

fruits: {
apples: "red",

}).getFromPath("food.fruits.apples");
//returns "red"
Hash Method: cleanValues {#Hash:cleanValues}
-------------------------------------

### Syntax
myHash.cleanValues(method);
### Arguments
1. method - (*function*) The function that each value in the Hash is passed. If it returns **true** the value is kept. Defaults to **[$defined][]**.
### Returns
* (*Hash*) - This Hash.
### Example
$H({
foo: 'bar',
something: 'else',
missing: null
}).cleanValues();
//remove all values < 0
$H({
a: -1,
b: 2,
c: 0,
d: -5
}).cleanValues(function(value){
if ($type(value) != "number") return true;
return value > 0;
});
Hash method: run {#Hash:run}
----------------------------
Runs all the methods that are values of the hash.
### Syntax

### Example
var myPage = {
init: new Hash({
setupNav: function(){
