put fopenmp in CXXFLAGS vs LDFLAGS, fixed MPI reduction ops in apsp/btwn_central, betweenness centrality now works

Corrected bugs in slicing

and work deep in progress for betweenness centrality

Conflicts:
	examples/btwn_central.cxx

Also made norms (except for the 2-norm) operate on the default ring rather than the specified algebraic structure

Corrections to some elementwise function functionality and new examples, one for custom bivariate functions and a crazy one for bitonic sorting

Fixed "universe" world, got rid of unuzed macros in util.h and reorganized contractions in fast 4D alg a bit

Made configure find fopenmp and and reordered some function definitions to make clang compiler happy

New model parameters based on 400 sec training run on 384 cores of Edison with 6 processes per node. They seem to do well for AQ CCSD/CCSDT with flat MPI or threads on 384 cores.

Turned off cubic models, increased threshold time for looking for a better mapping and set new init models

Added World copy constructor to allow proper passing of Worlds by value (although this iser is warned when DEBUG >= 1)

Turned off lapack routines when not building with -DTUNE

Setup configure file to make the config.mk file better documented and more easily modifiable to enable GPU support
