implement IsGenerated helper to filter out generated files Closes #17 Implements the IsGenerated helper function to filter out generated files using the rules and matchers in: - https://github.com/github/linguist/blob/master/lib/linguist/generated.rb Since the vast majority of matchers have very different logic, it cannot be autogenerated directly from linguist like other logics in enry, so it's translated by hand. There are three different types of matchers in this implementation: - By extension, which mark as generated based only in the extension. These are the fastest matchers, so they're done first. - By file name, which matches patterns against the filename. These are performed in second place. Unlike linguist, we try to use string functions instead of regexps as much as possible. - Finally, the rest of the matchers, which go into the content and try to identify if they're generated or not based on the content. Unlike linguist, we try to only read the content we need and not split it all unless it's necessary and use byte functions instead of regexps as much as possible.

- `GetLanguageByShebang` reads only the first line of text to identify the [shebang](<https://en.wikipedia.org/wiki/Shebang_(Unix)>).
- `GetLanguageByModeline` for cases when Vim/Emacs modeline e.g. `/* vim: set ft=cpp: */` may be present at a head or a tail of the text.
- `GetLanguageByClassifier` uses a Bayesian classifier trained on all the `./samples/` from Linguist.
It usually is a last-resort strategy that is used to disambiguate the guess of the previous strategies, and thus it requires a list of "candidate" guesses. One can provide a list of all known languages - keys from the `data.LanguagesLogProbabilities` as possible candidates if more intelligent hypotheses are not available, at the price of possibly suboptimal accuracy.

implement IsGenerated helper to filter out generated files Closes #17 Implements the IsGenerated helper function to filter out generated files using the rules and matchers in: - https://github.com/github/linguist/blob/master/lib/linguist/generated.rb Since the vast majority of matchers have very different logic, it cannot be autogenerated directly from linguist like other logics in enry, so it's translated by hand. There are three different types of matchers in this implementation: - By extension, which mark as generated based only in the extension. These are the fastest matchers, so they're done first. - By file name, which matches patterns against the filename. These are performed in second place. Unlike linguist, we try to use string functions instead of regexps as much as possible. - Finally, the rest of the matchers, which go into the content and try to identify if they're generated or not based on the content. Unlike linguist, we try to only read the content we need and not split it all unless it's necessary and use byte functions instead of regexps as much as possible.

Setting `ENRY_TEST_REPO` to a path to the existing checkout of the Linguist will avoid cloning it and speeds tests up.
Setting `ENRY_DEBUG=1` will provide insight into the Bayesian classifier built during `make code-generate`.

### Sync with github/linguist upstream
implement IsGenerated helper to filter out generated files Closes #17 Implements the IsGenerated helper function to filter out generated files using the rules and matchers in: - https://github.com/github/linguist/blob/master/lib/linguist/generated.rb Since the vast majority of matchers have very different logic, it cannot be autogenerated directly from linguist like other logics in enry, so it's translated by hand. There are three different types of matchers in this implementation: - By extension, which mark as generated based only in the extension. These are the fastest matchers, so they're done first. - By file name, which matches patterns against the filename. These are performed in second place. Unlike linguist, we try to use string functions instead of regexps as much as possible. - Finally, the rest of the matchers, which go into the content and try to identify if they're generated or not based on the content. Unlike linguist, we try to only read the content we need and not split it all unless it's necessary and use byte functions instead of regexps as much as possible.
