easy word cloud

##Features Based on word_cloud and word cloud generate, I created this easy word cloud.

Super easy to user. Compared to word cloud, easy_word_cloud provide a simplier interface and you do not need to have cython.
More effcient. Easy_word_cloud is more effcient with bigger canvas or a plenty of words.
Using weight instead of count. You can set the weiht to whatever you want( e.g. the count of word, log(count of word) ) only if you ensure it great than 0.
font size is strict liner with weight. In order to provide a more reasonable figure, the weight is liner with the font size. In word_cloud, the size of two words are not compareable because it doest not maintain the linearity.
Smart draw. I design a algorithm to smart choice font size with regard to the size of word, weight distribution of word and size of the canvas.
Unicode and python2/3 support.

##How to draw a word cloud? prepare the a list of word tuples. and then call the function

English

text = open(path.join(d, 'examples/constitution.txt')).read()
words = easywordcloud.process_text(text)
# to makes the weight more even
words = [(word, math.sqrt(weight)) for word, weight in words]  
easywordcloud.draw_word_cloud(words, width, height, 'examples/constitution.png')

output:

Englih with font Andale Mono

text = open(path.join(d, 'examples/alice.txt')).read()
words = easywordcloud.process_text(text)
easywordcloud.draw_word_cloud(words, width, height, 
                              'examples/alice.png', 
                              '/Library/Fonts/Andale Mono.ttf')

output:

Chinese

#python2
words = [(u'标签', 3), (u'云', 2)]
#pyton3
#words = [('标签', 3), ('云', 2)]
easywordcloud.draw_word_cloud(words, width, height,  'examples/chinese.png', None)

output:

Japanness

#python2
words = [(u'ワード', 0.7), (u'クラウド', 0.6)]
#python3
#words = [('ワード', 0.7), ('クラウド', 0.6)]
easywordcloud.draw_word_cloud(words, width, height, 'examples/japanese.png', None)

output:

NOTE: MAKE SURE THE FONT COVERS THE CHARACTERS YOU WANT TO DISPLAY If you are not on mac, you need to adjust FONT_PATH to point to some existing font.
