pmcx volume loading differs from mcx

[lkeegan]

When I ran the same simulation with pmcx and mcx I got different ouputs.

I traced the difference to a difference in the volume loading:

mcx applies a units factor when loading a MEDIA_AS_F2H volume:

mcx/src/mcx_utils.c

Lines 3237 to 3238 in d6c1f55

	f2h.f[0] = val[i << 1] * cfg->unitinmm;
	f2h.f[1] = val[(i << 1) + 1] * cfg->unitinmm;

while pmcx does not apply this factor:

mcx/src/pmcx.cpp

Lines 307 to 308 in d6c1f55

	f2h.f[0] = val[i << 1];
	f2h.f[1] = val[(i << 1) + 1];

When I added this factor to pmcx then the simulation outputs were the same.

both mcxlab and pmcx should be fixed. please update your pmcx to 0.2.4 to test.
