Update README.md
Made the warning from prior_flowClust more informative when no default K is given.
Added a function to validate prior_flowClust arguments. At the moment it checks to make sure flowClust and prior_flowClust have the same K.
Extra step validating arguments in the template in the call to gatingTemplate.
