Represents a generic random distribution.
This class allows to create random distributions by assigning arbitrary (non-negative) probabilities to its elements. The random number generator used is specified in RandHelper.

Adds a value with an assigned probability to the distribution.
If the value is already member of the distribution and checkDuplicates is true (the default) the given probability is added to the current. The probability has to be non-negative but values larger than one are allowed (and scaled accordingly when an element is drawn).

Return the sum of the probabilites assigned to the members.
This should be zero if and only if the distribution is empty.
