first round of hacked files for optigraph
Basic BFS now working,
Added arrayview and atomic int files.
Added 1st sanity test for BFS (not robust and poorly written)
bfs is working with computation
delete init
Merge branch 'master' into optigraph
Merged existing with master.
added optigraph to dsls folder
"up neighbors/down neighbors working"
computation for BC first half working
updated type signature of sum
Merge branch 'master' into optigraph
everything is screwed up
modifying BFS to match type signature
cleaned up type signature for bc
file I/O support in, bugs with undirected graph, 0 for nodeID input, need hash map still
changed i/o to have hash map
File I/O is now fast.  BC appears to match results from snap.  Delite compilation has mutability issues->next todo
bc working
