caching the results

[some-mthfka]

Hi, Andrii!

I have some vocabulary I translate quite often, so I thoght it would be quite handy to have basic caching implemented, because each translation may take up to a few bitter seconds and that's painful. What do you think about it?

i have implemented this, once this issue gets settled, I will eventually make a pull request to this repo

I think this feature is good, if it's not involving external tools, I think it should be worth to have it.
Would you like to send up the PR now?

@stardiviner Sure, will try to flesh it out and send the pr this week. No external tools involved.

@Grigorievich That's great. I'm glad to see people involving this project. 😄
