Extending the Set class for more flexible in-code use.
Added Element::giveEdgeLocationArray.
Added optional "set" input to GeneralBoundaryCondition.
Converted MixedGradientPressureNeumann to use Set instead of keeping its own list of elements.
Added W.I.P code for looping over sets and assembling element loads (will allow for b.c.s to specify a set and loop through that to assemble the load). Will be backwards compatible
Removed redundant "Domain" parameter from functions in ActiveBoundaryCondition (since it already knows the domain internally).
Fixed a few clang warnings (hidden functions instead of overloading).
Merge branch 'master' of github.com:Micket/oofem
