//Example Java Class to access the correlation value of two given words

//If the two given words are same, the correlation value is 1

//If any of the words is not a correctly-spelled word, e.g., "asdfg",
//or if there is no correlation value for the word,  the returned
//correlation value is -1 (error value)

//For valid words in the word-correlation matrix, the correlation value
//is between 0 and 1

//The program needs Jsoup library
