First attempt at three point coupling, runs but doesn't give correct results.
three point coupling scheme appears to work, documented, still needs to be properly integrated into the lb test case
fixed bug in three point couple, fixed test suite addition, lots of code duplication
small fix of test case for Shan Chen to pass test
final touches on three point coupling, changed a variable name to avoid namespace conflict with global my_left
commit to merge with master
almost finished different types of noise, still issues with chopped Gaussian
finished the implementation of 3 point LB coupling for the GPU and the addition of two types of Gaussian noise with docs
Merge remote-tracking branch 'upstream/master' into workingBranch
trying to recover lost directory
fixed bug in build system from name change, removed warnings, bug in lbgpu flatnoise
Fixed problem with flat noise using the GPU LB, limit make check to 8 procs for mass-and-inertia.tcl to work, fixed bug in Gauss noise for NPT
Cleaned up code a bit
removed unnecessary ifdef
