prior creates a prior distribution for fitting a PET or
PEESE style models in RoBMA. The prior distribution can be visualized

The truncation is automatically set to the bounds of the support.
prior odds associated with a given distribution. The value is passed into the model fitting function, which creates models corresponding to all combinations of prior distributions for each of the model parameters and sets the model priors odds to the product of its prior distributions.
prior_PEESE return an object of class 'prior'.
