File Reader/Writer

Simple wrapper for the static methods Files.readAllLines and Files.write, bringing into simple classes that can be injected into code using Dependency Injection allowing them to be mocked during testing without touching the real filesystem.

Assumptions

• All files will be read and written in ÙTF-8.
• When reading a file lines breaks will be replaced by the newline character.
• When writing a file it will be truncated first.
