Issue in mcx_main_loop

[lukasm91]

I was looking at your code and I found this line:
https://github.com/fangq/mcx/blob/master/src/mcx_core.cu#L1332

Is this correct? Shouldn't this be (v->y > 0.f)-(v->y < 0.f)? The same also for L1333.

wow, can't believe this survived over 2 years! thanks for pointing this out! I will fix it right away.

BTW, the bug was introduced in this commit:
29ea426

[fangq]

the issue is now fixed. the mcx_nextafterf() function increases or decreases the selected photon positions by eps (~1.19e-07 for float). This bug does not alter the simulation results significantly, but may introduce redundant calculations at the boundaries.

thanks again for reporting this. let me know if you see additional issues.
