/**
* @author Mark Larkin, Conway Institute, UCD. mark.larkin@ucd.ie
*
* This widget was created to get around the problem that the QFileDialog cannot
* remember the last directory visited. The QFileDialog doesnt know the last
* directory it has been to. So I developed a wrapper class to make it easier.
* It uses a global string defined in globalLastDir.h
*
* Changes:
*
* 03-02-07,Nigel Brown(EMBL): copied getOpenFileName() into two versions
* getOpenDataFileName() and getOpenParamFileName() and changed lastDir to
* lastDataDir and lastParamDir. These maintain two different working
* directories for data files and for parameter files, respectively.
*
* 03-02-07,Nigel Brown(EMBL): changed getSaveFileName() to
* getSaveDataFileName() which now takes a file suffix as a hint to the file
* to be opened. Added lastBaseName to hold last data file basename (ie., no
* suffix). Removed 'globalLastDir.h'dependency by making lastDataDir,
* lastParamDir, lastBaseName static members.
