## Methods

#### filterOutItem

Given a list and an item, returns a copy of the list absent said item.

```js

var listUtils  = require('alien-node-list-utils'),

    list       = ['a', 'b', 'c', 'd'];

    

listUtils.filterOutItem('b', list); // ['a', 'c', 'd']

```

#### filterOutObject

Given a key, value, and list, returns a copy of the list absent the object(s) which match said k/v pair.

```js

var listUtils = require('alien-node-list-utils'),

    list      = [{ foo : 'bar'}, {baz : 'bat'}, {buz : 'but'}];

    

listUtils.filterOutObject('baz', 'bat', list); // [{ foo : 'bar'}, {buz : 'but'}]

```

#### maybeDropLastItem

Given a qualifying drop length and a list, returns a new list who's last item is dropped if the list 

length exceeds or equals provided drop length

```js

var listUtils = require('alien-node-list-utils'),

    list1     = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'],

    list2     = ['x', 'y', 'z'];

listUtils.maybeDropLastItem(5, list1); // ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i']

listUtils.maybeDropLastItem(5, list2); // ['x', 'y', 'z']

```

#### sortAsc

Simple ascending sorter function

```js

var listUtils = require('alien-node-list-utils'),

    list      = ['b', 'd', 'a', 'c'];

listUtils.sortAsc(list1); // ['a', 'b', 'c', 'd']

```

#### sortDesc

Simple descending sorter function

```js

var listUtils = require('alien-node-list-utils'),
