%GENDB - constructs a gendb object.
%[db] = gendb(dbName)
%All operations on the database will be performed using the
%ADT object which is passed to them as the first parameter.
%Exemples:
%  db  = gendb('yoho');  -  loads YOHO  database.

  db.name =name;

  db.path = defaultPath{1};
  format = textread([instancePath ,'\format.txt'],'%s');
  db.format = format{1};
  metaNames = textread([instancePath ,'\meta_names.txt'],'%s');
  db.metaNames = metaNames;
  
  for ii=1:length(metaNames)
      enterie.(metaNames{ii}) = '';
  end
