Torch7 ports (Was: Wxlua / Zbstudio)

[Raymond Cheung]

I'm using FreeBSD 11.0-ALPHA5 to test.

If I use clang/clang++ with the official distro, then nn.test() are passed
but torch.test() are error/failed.

If I use gcc/g++ for pkg/torch and others with clang/clang++ (and run exec
'/usr/local/bin/lua51' -e  ...), then two tests (max and min) of
torch.test() are error/failed:
max
error in torch.max (value) - NaNs
BOOL violation condition=false

min
error in torch.min - NaNs
BOOL violation condition=false

But I can't require 'nn':
install/lib/lua/5.1/ffi.so: Undefined symbol "cpow"
