/**
 * This switcher can translate all kinds of objects given to a boolean value.
 * 
 * This is necessary for CSV files - mostly for the PRIVATE flag, which 
 * may be -depending on the Outlook version- either "true", "yes", 
 * "private" or whatever... so, rather than calling it "BooleanFinder",
 * one might call it "TruthSeeks", because it finds out whether a certain 
 * value might be translated to <code>true</code>, considering everything 
 * else <code>false</code>.
