dst v 1.3.0
- added utility functions 'matrixToMarray' and 'marrayToMatrix' to execute the product space conversion of multidimensional data represented by a matrix, and vice-versa.
- debugging of function 'extmin' (extension of data to a larger product space).
- debugging of function 'elim' (reduction of a product space by elimination of one variable).

dst v1.0.0 (Release date on CRAN: 2018-04-25)
Changes from version 0.3:
- Added a vignette: The Monty hall Game, an introduction to belief functions.
- functions (new and updated):
-- addTobca: New function. Adds some elements of 0 mass to an existing mass function.
-- bca: New version. Sets a class named "bcaspec". Parameters added to work with definitions on product spaces (relations).
-- bcaRel: New function to define a belief function on a product space.
-- belplau: Calculation of measures of belief, plausibility and ratio of plausibility.
-- decode: utility function
-- dotprod: utility function
-- double: utility function
-- shape: utility function
-- encode: New utility function. Convert a value to its representation in another chosen base.
-- reduction: utility function to obtain the summary of a vector for any operator
-- dsrwon: Combination of two mass functions
-- elim: This is a new function. This function works on a relation defined on a product of two variables or more. Having fixed a variable to eliminate from the relation, the reduced product space is determined and the corresponding reduced bca is computed.This operation is also called "marginalization".
-- extmin: Extension of a relation to a greater product space
-- inters: Intersection of two tables of propositions
-- nameRows: New function: Using the column names of a matrix to construct names for the rows
-- nzdsr: Normalization of results from Dempster's rule of combination.
-- productSpace: New function. Product space representation of a relation
-- plautrans:Plausibility transformation of the singletons of a frame
-- tabresul: Prepare a table of results.
- Removal of obsolete functions:
butLast, combmasses, dempster, initsing, rplau, transfo
