//takes a line of characters and breaks the line up into words by creating a

//new string of only alphabetical characters: Note: I did this by first

//breaking the string into individual words separated by spaces, and then used

//the function stripSpace to remove anything that wasnt an alphanumeric

//character using the built in isalpha function.

//string

void getPriority(string line);

//The line is the tag, without the first <. This method uses the line to

//determine the current priority as follows:

//If the first 5 characters in the line match the word title (I used

//line.compare for this), or the first 2 characters match either h2 or h2,

//then the current priority is set to 1. If the first 2 characters are

//anything between h3 and h6, then the priority is set to 2, and if its

//anything else, its set to 3.

// stopwords in the array of stopwords from the linked list (using the
