     'loadFromDB' in package 'tkfi'  This method allows to load objects
     once stored in a database back to the R workspace. Objects from
     the type 'EexprSet' can be stored into a PostgreSQL database with
     the function 'publishToDB'. To check for available objects in the
     database call the 'dbGetExperimentInfo' function by submitting the
     connection object to the database.
