int p: The score
int len: The article length
int numtemplates, int numlinks, int numimages, int numcomments: Self explanatory (if you don't get it, num=Number Of
int numelinks: Number of external links

int sOccC(String str, String substr): Returns the number of times substr is in str (sOccC = String Occurence Count)
