[FEATURE] FidoAdapter

Protein inference tool: FidoAdapter
Tests are added into the SEARCHENGINES folder.
is this supposed to be checking whether fido_results contain a protein accession? If yes, this is very dangerous, see http://www.cplusplus.com/reference/map/map/operator[]/ - what this code will do is _insert_ a new element into fido_results and I am not sure whether this is what you want. Please use
`if (fido_results.find(protein_accession) != fido_results.end() )`
