ibelief 1.1
--------------------------------------------------------------------------------
* Add the function LCRule for creating bbas from probabilities using Least-Committed Principle.
* Change the form of the input/output mass matrix for function discounting. Now for both the input and output mass matrices, each column is a bba. If there is only one bba to discount, the input and output bbas are both vectors.
* Fix the bug that qtow function could not work for dogmatic belief functions.
* Fix the bug that some FMT functions could not produce an output.
ibelief 1.2
--------------------------------------------------------------------------------
* Change the form of the output vector for the combined mass in DST function. Now the output for all the type of bba generated is a column vector.
* Fix the bug of RandomMass function brought by the base::sample function.
* Add three types of mass in RandomMass function, consonant bbas and non-dogmatic consonant bbas (both with nested focal elements), SSFs.
* Modify the function DST to be more optimized.
* In DST function, the combination rules LNS and LNSa are added.
* Change the name of the function LCRule to LCPrinciple
ibelief 1.3
--------------------------------------------------------------------------------
* Add a kind of FMT function converting mass function to contour function
* Add a decison rule (criterion 6, the distance criterion) in decisionDST function
