The section type slash-issue

Section types are currently used as a classifier of sections independent of their hierarchical order, e.g.:
the section "_UtahArray_", and the section "_TungstenElectrode_" could both have the section type "_recordingdevice_" even if they are located at different branches and levels of an odML document.

Via a slash separator one can also build a type hierarchy, e.g.:
section "_TungstenElectrode_" with type "_daq/hardware/recordingdevice_"

If one searches now for the the type "_recordingdevice_" one should still get the section "_TungstenElectrode_" which is currently not the case or at least I don't know how.
