A command that calculates the "additive constant" from the selected Dissimilarity.
Distances d_{ij} will be obtained from dissimilarities δ_{ij} according to:
distance_{ij} = dissimilarity_{ij} + additiveConstant 
We use a procedure by Cailliez (1983) to solve the "additive constant problem", i.e. find the smallest additiveConstant such that all distance_{ij} in the above equation have a Euclidean representation.
