// paths that lead to users of the tools
var a = g.V('sass').In('uses')
var b = g.V('sublime text').In('uses')

// Who uses both tools
var c = a.Intersect(b).ToArray()

// What tools are used by all of those people
var software = g.V.apply(this, c).Out('uses').ToArray()

// Convert an array to a hash with counts
var results = {}
_.each(software, function(s){
  if(results[s]==null){ results[s]=0; }
  results[s] +=1;
})

// Remove search terms
delete results['sass']
delete results['sublime text']

// Emit results
g.Emit({tools: results, users: c})
