[Neos] Creating a New FlowQuery Operation

[nikos]

Hi Dmitri

Thanks ${q(targetNode).find('[instanceof TYPO3.Neos.NodeTypes:Headline]').first()} is perfect, don't know how I missed that.

I am curious a little of how it determines the sort order of the collection returned. Seems to be using "sortingindex" which is on the database but I 
am not sure you can "override that" and it can lead to unexpected behavior eg

for the following structure

main
   Heading A
     section1
       Heading B
       section2
         Heading C
       Heading D
   Heading E

I get the following :
     A, B, E, D, C

whereas I would have expected:
    A, B, C, D, E (depth first search)
or
    A, E, B, D, C (breath first search)

For what I am after at the moment that doesn't matter but could be useful to understand.

Thanks anyway and also for the examples.

Nikos
