yaml test

added yaml test
in progress CREATE Only

Create Table As for Create only case  somewhat working, tests added but
error occurs because transaction expected to be open besides that
working fine
Copy the internal indexes two

pkless tables have an internal index for their primary key
Copy the internal columns too

we need to copy the internal column containing the hidden pk also
Check duplicate position against non-internal

getColumn(int) looks at the non-internal positions, so compare to
that size before accessing
Added a test
Ignore nohup.out

this gets automatically created when you run the sqllayer in the
background, just as a log
Remove akibanPK if adding a primary key
Revert "Remove akibanPK if adding a primary key"

This reverts commit ef13450f0def7d01f28704817a9bbd1bc0246a1f.
This isn't where we should do this because it leaves a dangling
column in the db, we need to remove it up at the alter table level
Create Only complete

added new flag for serverStatement.TransactionNode to fix transaction
issue
tests added to yaml test, all pass now
cleaning up

cleaing
If adding PK to PKLess table, drop akiban pk
Allow dropping of internal columns

I'll need to go back and fix this so that user can't somehow drop
the internal column
cleaning

more cleaning up
Include internal columns size on add column pos

When adding a new column, the auto position needs to be calculated
including the internal columns
Added some PKLess alter table tests
last bit of cleaning
We don't support positioned add column at all
Added test for dropping akiban column (Ignored)

Currently failing on master, will need to add a card
Fixed up adding primary key test
