The Config class now has a method getValues() to retrieve in a vector of type T all values whose keys match a given pattern. This makes it possible to retrieve in one call all the Input::STATIONx values even in the case of discontinuous numbering (issue 341) as well as easily get the number of stations declared in io.ini (issue 220). This number of stations is not guaranteed to work (since some plugins don't list the input stations in io.ini) but should guide memory allocation in user code anyway.

A reference has been fixed in Suntrajectory, redundant errort checking has been removed from GeneratorAlgorithms.
