Indentation oversight in summarizer.py

[dainiussa]

Hi, I believe there is a bug in sbs function at summarizer.py. In the for loop at line 73, the code loops through words in sentences but these if statements are outside of the loop:

if word in keywordList:
        index = keywordList.index(word)

if index > -1:
        score += topKeywords[index]['totalScore']

Therefore, the scores are only calculated for the last words of each sentence.

确实，以上几行应该后退4格，被包括到word的for循环内
