read me for testing data set cuse
Exec2 autoconverts VA to Frame
Merge branch 'master' of github.com:0xdata/h2o
Remove some debug prints, shrink test case
Fix parsing test/test_quote.cvs

During parser-guessing, fields with an initial quoted section, followed
by more text (still in the same field) will not directly cause a
bailout.  Also, when the parser-setup guess fails, have the parser
politely throw a IllegalArgumentException (of a zero-column CSV) instead
of an assertion fail.
More debug prints removed
Pay attention to single_quote flag during CSV guessing

Guess col splits & counts either looking at or ignoring single-quotes
based on the setup flag.
