Extended JSON Parsing / Scraping in Python3
"""
Rationale: Some websites make it difficult to scrape from by obfuscating their otherwise JSON data with
things such as unquoted object keys, concatenated strings, comments, etc. which are all valid JavaScript
constructs but invalid JSON. This usually forces would-be web scraper developers to emulate an entire
browser just to mine the data, which apparently is a fairly successful deterrent. This script parses the
JavaScript AST without executing any potentially malicious JavaScript DRM code, and correctly parses a
number of valid JavaScript constructs into a Python dictionary.
It also provides methods to quickly download a web page and search for a global variable using pyquery.
