Documentation does not clearly specify that columns are added to master problem

[rowtricker]

In ColGen, the documentation for the method invokePricingProblems(long timeLimit) states the following:

 /**
     * Invokes the solve methods of the algorithms which solve the Pricing Problem. In addition,
     * after solving the Pricing Problems and before any new columns are added to the Master
     * Problem, this method invokes the {@link #calculateBoundOnMasterObjective(Class solver)
     * calculateBoundOnMasterObjective} method. 
     * 
     * @param timeLimit Future point in time by which the Pricing Problem must be finished
     * @return list of new columns which have to be added to the Master Problem, or an empty list if
     *         no columns could be identified
     * @throws TimeLimitExceededException TimeLimitExceededException
     */

It is currently somewhat unclear from the documentation if the columns are indeed added to the master by this method or not. This may be important, as adding columns to a model most likely makes querying information (like objective value / solve status) impossible.
