Naming Conventions

• The visibility of a name outside a package is determined by whether its first character is upper case.
• Prefer simple name instead of a long name.
• Package name should be good: short, concise, evocative. By convention, packages are given lower case, single-word names; there should be no need for underscores or mixedCaps.
• The package name is the base name of its source directory; the package in src/encoding/base64 is imported as "encoding/base64" but has name base64,
• Go doesn't provide automatic support for getters and setters. Use Owner as an example, the getter method should be called Owner (upper case, exported), not GetOwner. A setter function, if needed, will likely be called SetOwner.
• By convention, one-method interfaces are named by the method name plus an -er suffix or similar modification to construct an agent noun: Reader, Writer, Formatter, CloseNotifier etc.
• The convention in Go is to use MixedCaps or mixedCaps rather than underscores to write multiword names.
