* A sample implementation of a plugin for handling Mnemonic phrases. Any library can easily be
|
|
* plugged into the SDK in this manner. In this case, we are wrapping a few example 3rd party
|
|
* libraries with a thin layer that converts from their API to ours via the MnemonicPlugin
|
|
* interface. We do not endorse these libraries, rather we just use them as an example of how to
|
|
* take existing infrastructure and plug it into the SDK.
