Sorter to sort one level of input
===================================

This parser is adapted from SortText and used to sort text lines which are delimited by a special symbol.  The
sort direction and the column to sort can be specified. For the sort column the type can be specified as "text"
or "date". The delimiters are omitted in the final output.

Defaults are
delimiter=''
column='1'
column_type='text'
sort_direction='up'

delimiter is the empty string so that a normal text search is done by default.

Install
-------
Put it in your wiki/data/plugin/parser/


Example
-------

{{{
#!Sorter column=2,column_type=date,sort_dir=up,date_format=%d.%m.%Y
* | B | 1.1.2005
* | A | 1.2.2006
* | D | 4.1.2005
* | C | 5.4.2000 
}}}

Result::
* C 5.4.2000 
* B 1.1.2005 
* D 4.1.2005 
* A 1.2.2006
