Separate node module with core functionality.

[ritz078]

Would you like to create a separate node module for this ? This seems great and I would love to use this in https://github.com/ritz078/snape . Let me know if you need any help.

We've completed the abstraction of our core logic into a separate module. We module can be found at https://github.com/gielcobben/caption-core.

Currently caption-core supports:

• Downloading subtitles
• Searching by files
• Searching subtitles by search query (supports multiple sources)
