new USER-INTEL package

Hi all - released a new USER-INTEL package in a 15Aug14 patch today,
authored by Mike Brown at Intel. It has a handful of pair styles
that can be used in either of 2 modes:

a) optimized for Intel CPUs via vectorization, can also compute

forces in single, mixed, double precision

b) optimized to run on Xeon Phis (Intel coprocessors)

The package can also be used in tandem with Axel’s USER-OMP
package to run other styles (bond, fix, kspace, etc) via OpenMP
threads in conjunction with the new Intel pair styles.

Mike plans to add more pair styles in the future.

A new examples/intel directory has test scripts you can run.
