NOTE!
- The extractor type was added in v2.17.6 and allows you to apply two parsers to a column:
			- In this demo, the last column contains select dropdowns that have "good", "medium" and "bad" options.
- So there is a need to use a parser to extract content from the selected option within the select and then use the grades parser to give each grade a sortable value.
- Thanks to TheSin- for adding this functionality!
 
- The extractor is always used before the parser.
- Individual columns can be modified by adding the following (they all do the same thing), set in order of priority:
			- jQuery data data-extractor="select".
- metadata class="{ extractor: 'select'}". This requires the metadata plugin.
- headers option headers : { 0 : { extractor : 'select' } }.
- header class name class="extractor-select".
 
- jQuery data
