* This data processor can be used for processing data for the content elements which have split contents in one field

*
* Example field data:
*
* This is bullet 1, This is bullet 2, This is bullet 3
*
* Example TypoScript configuration:
*
* 10 = TYPO3\CMS\Frontend\DataProcessing\SplitProcessor
* 10 {
* if.isTrue.field = bodytext
* delimiter = ,
* fieldName = bodytext
* removeEmptyEntries = 1
* filterIntegers = 1
* filterUnique = 1
* as = bullets
* }
*
* whereas "bullets" can be used as a variable {bullets} inside Fluid for iteration.
