ConditionalScore-class: Class for conditional scoring function
Description
ConditionalScore is an abstract class for conditional scores.
It requires the two slots distribution and prior that
determine the data distribution and the prior distribution for the effect
parameter. When defining a specific ConditionalScore, a corresponding
method evaluate needs to be defined, too.
Any ConditionalScore can be transformed to an unconditional
IntegralScore by means of the method expected.
