Calculate the Value of a Fuzzy Number
The calculation of the so-called value is one of possible methods to deffuzify a fuzzy number.
## S4 method for signature 'FuzzyNumber' value(object, ...)

The value of A (Delgrado et al, 1998) is defined as val(A) := int_0^1 α(A_L(α) + A_U(α))dα.
Returns a single numeric value.
