/**
* Add text box's at the top of columns in a table to allow
* fast flltering of rows underneath each column.
*
*
* @name columnFilters
* @type jQuery
* @param Object settings;
* wildCard : A character to be used as a match all wildcard when searching, Leave empty for no wildcards.
* notCharacter : The character to use at the start of any search text to specify that the results should NOT contain the following text.
* caseSensitive : True if the filter search's are to be case sensitive.
* minSearchCharacters : The minimum amount of characters that each search string must contain before the search is applied.
* excludeColumns : A zero indexed array of column numbers to not allow filtering on.
* alternateRowClassNames : An array of alternating class names for each row returned after filtering in order to keep odd and even row styling on tables. Maximum of two items.
* underline : Set to true if the script is to underline the search text whilst filtering is in progress... good for tables with lots of rows where the filter may take a second. (not in Opera)
