create supvec class
create filters for sampling datas
create sensitivecontextset

defined by user by now, then it can be decided by system accroding to
complex structure
create sensitivecontextset loaders

by now, only support txt sensitive context set, then can add other
loaders extends the father class SensitiveContextSetLoader.
different type loaders for trainning data

by now, support for TxtLoader, in future, you can add other loaders
extending father class DataLoader
loader for trainning data

father class
create class SupVecTrain for trainning suppression vector

father class, it can be extended by different sucessors of different
trainning methods
change positions for some classes
change positions for some classes or interfaces
model for training historical data
make the object can be cloned
class cycle includes constants about training cycles
GreedyTrain class

by now, the method of training suppression vector
