failing parent pointer test and starting to imlement (but this is crap)
Merge branch 'master' into navigation
add a toParentPointer method to crate the parentPointer array from flat with depth
add setChildren to Node
support correct unwrapping for this test in SimpleNode
add a toStructure algorithm which does the same as parent pointer but converts the children as a nested array
add hard dependency to testdata
add a little hook to the toStructure to extract paths and else
