Korean learning tool - Vocabulary recall and study

I  have created this post/Tool in order to help me and those learning Korean as a foreign language.

You can find a description of the usage of this at my github.

Some collections of words were taken from a group of online books at EFKA. Below I have included an online Korean-English dictionary to query if there are doubts while studying.
