Leetcode Analyzer

Add a graph for visualization of number of question per tag and also add a contest history table

Features: - simple design - update on every reload - Graph visualization with hover effect of showing tag name - User can check how many question already done on specific tag just by hovering on it - A Table which shows Contest history with rank and score - Faster updation than leetcode real contest time graph Because Leetcode officially doesn't provide any feature by which user get to know how much question already solve by them on specific topic so by this extension we can have that feature on Leetcode account page and this extension doesn't require any username and password. More feature coming soon.
