Merge branch 'master' into nomosoa
leaving myself notes for later
added taskIndex_x,y,z and taskCount_x,y,z
taskIndex_x,y,z are passed to the task
launch now passes the right info into tasking
fixed tasksys.cpp for 3d tasking
changed notation, task[Index,Count]_[x,y,z] -> task[Index,Count][1,2,3]. Change launch <<< nx,ny,nz >>> into launch [nx,ny,nz] or equivalent launch [nz][ny][nx]. Programmer can pick the one the is liked the most
tasksys cleaning
changed notation form taskIndex1,2,3 -> taskIndex0,1,2
added tests for 3d launch
Merge branch 'master' into nomosoa
Add dynamic dispatch support for export functions with pointers to varying data as arguments
added description for multi-dimensional tasking
Merge pull request #683 from ifilippov/trunk
