A JavaScript equivalent of PHP's str_getcsv

    //an escaped enclosure even if followed by the delimiter and another enclosure mark)

Please note that php.js uses JavaScript objects as substitutes for PHP arrays, they are 
the closest match to this hashtable-like data structure. 

Please also note that php.js offers community built functions and goes by the 
[McDonald's Theory](https://medium.com/what-i-learned-building/9216e1c9da7d). We'll put online 
functions that are far from perfect, in the hopes to spark better contributions. 
Do you have one? Then please just:

### Example 1
This code
{% codeblock lang:js example %}
str_getcsv('"abc", "def", "ghi"');
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
['abc', 'def', 'ghi']
{% endcodeblock %}
