RE Engine error with sub()

[Maurice LING]

Solved it. Instead of modifying Replacer class, I've made another class 
which initiates a list of Replacer objects from a list of substitution 
rule files. And then iterates through the list of Replacer objects and 
calls upon their own substitute() method. It seems to work.

Thanks for all your advices.

Cheers
Maurice
