Profanity Filter: Determine if a text contains many obscene words

This class can be used to determine if a text string contains too many obscene words, based on ratings of each word, frequency of use, etc.

It parses a given text and checks if it uses words that are part of an obscene words list. It can also look for variants of the words and plural forms of the listed English words. This list can be modified, the ratings for each word changed, etc.

The class returns a score number that may be used by applications to take decisions on whether the text is tolerable for the intended use.
