Allow the specification of a logging interface

[raouldevil]

Many gems allow for the specification of an interface which can handle logging of any important information and errors. For example, the Xeroizer gem allows this in an initializer:

Xeroizer::Logging::Log = My.logging_interface if Rails.env.production?

Is it possible to implement this for this gem as well? @SerKnight I am willing to attempt the PR for this if you are OK with me to do so.
