New version of UG documentation for EK.
Merge branch 'master' into Merged_EK_newer

Merged with master to ensure everything is up to date.
Necessary changes to get the lb_planar_embedded_particles.tcl testcase to pass on 3 cores, to fix a compiler problem for the nocheck-maxset, and to fix the actual problem in the code that that problem indicated.
Fix to make the make distcheck work.
Merge pull request #127 from jdegraaf/Merged_EK_newer
