recognise the code language using word2vec or word2doc neural network model

1. git clone some CPP and Python program and put them in directory ./data/crawl_data/CPP and ./data/crawl_data/Python or execute spider.py file to crawl code file from github automatically
2. extend dict file in ./data/dict/dict;put key words in the file dict.raw for every code language
3. run the script run.sh and the result will be written in RESULT

1. crawl more code data from github or modify spider.py file to crawl data automatically
2. collect key words for every language and form dict file
