Library documentation

[jjzazuet]

Hi. This library looks very promising.

Whenever possible, please add some documentation with:

• A general overview on how the library is designed to work.
• Some high level examples on how to implement common use cases (i.e. sending money, balance checking, multisig transactions, etc.).
• How to test code written using this library.
• Security considerations while using the library.

Thanks for your time!

We may add documents later.
