start working on new idea for Pagerank w/ vectors aligned w/ vertices
mirror rename from master (pagerank->pagerank_old,pagerank_new->pagerank)
fix pagerank build targets
finish making changes to use Graph<PagerankVertex> instead of 'vector'
Merge branch 'master' into new-pagerank

Conflicts:
	applications/pagerank/pagerank.cpp
	applications/pagerank/spmv_mult.hpp
Get it to compile by stripping out all the old stuff (broke pagerank_old)
nested delegates: enroll initial one, send completion on final one
less verbose logging, add '--metrics' flag to dump metrics to stdout
make pagerank terminate: v.adj_iter may be broken
fix mixup of vertex id and adjaceny list index
mixed up local_adj index & global vertex index (again)
Merge branch 'master' into graph-refactor
don't need to synchronize 'call' in remoteSpawn
fix forall(GlobalVector) (make it a friend function)
Some weirdness in GlobalVector to make GCC like it.
Make forall(adj...) work from any core
igor_common: work with copy of 'exes' list
distcc_ninja: set number of parallel jobs based on nnode
fix Grappa::memcpy to handle void*
fix how graph500-generator is linked
