//with the 4th parameter set to true, it will print out the total number and also, write each article to file.
//the txt files will be in the current working directory under a directory named {your query}  in this case it's javascript
//some will return zero kb.  im not sure what the hell is going on with that(nyt server error status 500), but you can get most articles this way.
//the 5th paramter is to specify the maximum number of articles to write to file.  This is pretty helpful when queries like "computer" have over 120000 results
 
//in the future i'll probably refine the search paramters a bit to get more accurate results such as the ability to search for all articles containing "computer" in the "technology" section of the NYTimes
