how to use this classes:

1. download all the files, classifier.php until all utilities and *.srl file
2. replace all the file in one folder. example in folder 'PHPclassifier'
3. create a new folder in folder 'PHPclassifer'. name that folder with 'cat'

in folder 'cat', you add 2 or more folder that are named with your 'category name'.

example, i have two category, spam and notspam, so i make 2 new folder in folder
'cat', first folder name 'spam' and the second folder name 'notspam'. 

in folder 'spam', i have *.txt file(name is free, blabla.txt), this txt file contain
the text that we classify spam before. this text will be used by the trainer.

same with the second folder 'notspam'.
