just updated to use cB.hex instead of cB in case people don't like that.
still fails. https://0xdata.atlassian.net/browse/HEX-606
Merge branch 'master' of github.com:0xdata/h2o
just the exec with colswap plus factor. oddly, the presence of whitespace seems to affect it  (in the exec expression)..this passed if I removed the whitespace (introduced by splitting the exec across lines in my python code)
