    o   new function `truePrevMulti2`, implementing a covariance scheme for
	estimating TP from AP obtained with multiple tests

    o   new function `define_prior2` to show the definition of the priors used
	by `truePrevMulti2`

    o   definition of `x` in `truePrevMulti` is reversed; first element of `x` now
	is the number of samples positive on all tests, last element of `x` is the
	number of samples negative on all tests

    o   'definition' functions renamed to `define_x` and `define_prior`

    o   functions `truePrev` and `truePrevPools` lost args `conf.level` and `plot`

    o   function `betaPERT` lost args `p` and `plot`

    o   print method for objects of class `prev` no longer shows percentages

    o   various code cleanups and small bug and typo fixes
