Consider property paths for fetching SBOL and other recursive operations

[cjmyers]

Property paths such as the one below appear to be a promising way to do recursive operations. This might include things like recursive fetch, recursive delete, etc.

PREFIX sbol: <http://sbols.org/v2#>

SELECT distinct ?cd WHERE {
       <https://synbiohub.org/public/iGEM_2017/iGEM_2017_Parts/1> 
         sbol:member/((sbol:component)/sbol:definition)* ?cd
}

not sure what this means, as there is recursive things already

This could be really useful
