introduce BoundaryElementsAlongPolyline and BoundaryElementsAlongSurface to own boundary elements
[WIP] test codes for boundary element search
skip internal elements also in face search
rename BoundaryElementsAlongSurface to BoundaryElementsOnSurface
reverse the 4th edge's node indeces in a quad element
add getConnectedNodeIDs to collected node IDs used in a given set of elements
BoundaryElementsAlongPolyline returns elements sorted according to their distance to the starting point of the polyline
