Refactor code to use interfaces

[chapinb]

Is your feature request related to a problem? Please describe.

This project is difficult to integrate in to other code bases as a library:

• The entry points are unclear
• The steps required to complete an action are not intuitive
• You need to review the source code in addition to the documentation to determine how to leverage the library

Describe the solution you'd like

A potential solution is to use interfaces and re-structure the library to have a clear workflows for common use cases. Some use cases include:

• Resolving an IP address against one or more resolvers
• Extracting an IP address from an input using a parser
• Leverage utilities that can convert IP addresses to integers, detect that they are BOGON, etc.
