changes quote-quote to double quote, make liuqe option supersede from start, add ipol and i_pol, fix new gas ref

While adding i_pol I added ipol and fixed all '''' to " and try to simplify some parts

Since it fixes some other things and many changes, I will deploy for expt on Tuesday morning to have tests on larger scale and will be in control room
