just-debounce
=============
just a basic debounce function
# Why?
I searched npm and the first 3 pages of results for "debounce" did not have a
small correctly implemented version of debounce
# Usage
### arguments
* `fn`: the function to debounce
* `delay`: debounce delay in ms
* `at_start:` if true, the function will be called at the beginning of the
delay rather than the end
* `guarantee`: ensures the time before the next call the `fn` is not greater \
than the delay period.
```javascript
var db = require('just-debounce')
var debounced = db(function(v) {console.log(v)}, 100)
debounced('hi')
debounced('hi')
// logs 'hi' once after 100ms
```
```javascript
var db = require('just-debounce')
var debounced = db(function(v) {console.log(v)}, 100, true)
debounced('hi')
debounced('hi')
// logs 'hi' once right away, but not a second time. calling after 100ms will log again
```
```javascript
var db = require('just-debounce')
var debounced = db(function(v) {console.log(v)}, 100, false, true)
debounced('hi')
setTimeout(function() {debounced('hi2')}, 80)
// logs 'hi2' once 100ms after the first call to debounced
```
