demetra_m have different columns with identical names

[TanguyBarthelemy]

When we extract output from jdemetra (with the cruncher or with the GUI), the matrix demetra_m has different columns with the same name.

For example here is a matrix demetra_m generated with the GUI in version 3.
The name q is used twice in the colum (Y) and in the column (JL).

Also there are a lot of unamed columns.

This can be confusing for the user, especially as some of the colums may contain objects of the same type (integer, character, etc.).
Furthermore, reading this matrix with another programming language can be very challenging (since the column of a data.frame in R must all have a and an unique name).

Is it possible to rename the column or to add a prefix / suffix to indicate in which group this variable comes from (for example arima.q and statsQ.q)?
