/** org_edge_strg_symb( +Org, +Symb1, +Symb2, -W )

Organism abstraction interface to STRING database test.

Assumes underlying predicates have their symbols sorted, and that Org is already passed through bio_organism/2.

==
?- org_edge_strg_symb( hs, 'LMTK3', Symb2, W ).
Symb2 = 'AATK',
W = 359 
...

?- org_edge_strg_symb( mouse, 'Ltmk3', 'Aatk', W ).
W = 308.
