Work with many rings and fluid
Added cuda version with forces computations for bonds and angles. Checked that works correctly
Added non-newtonian force computaion to the cpu code. didn't validated it
Removed up/up_force, use std transform instead since it might be changed to thrust transform later
fixed mistakes in the code, yet dpd doesn't work correctly
renamed cuda rbc ring and minor changes in rbc_ring
Added reduce to the DPD forces computation
Force computation works correctly, it natoms must still be pow of 2
and must not exceed 1024.
for pbc use for_each instead of loop
Modified makefile and moved to gpu integration, pbc
Added some bounce-back on levelsets, just a draft
vanilla walls
DPD force for the ring was added. Doesn't work yet
vanilla-sphere
tomato sandwich revisited
Added first version of FunnelObstacle. It is not very precise now
Added read/write check
ready for kirill
Merge branch 'kirill' of https://github.com/rossinelli/CTC into kirill

we need kirill obstacle
makefile for funnel obstacle
