Add space around operators
Rubocop: allow SpaceAroundEqualsInParameterDefault enforcement
Add spaces around equals operators for parameter defaults
Rubocop: allow AccessModifierIndentation enforcement

The default style is "indent."  Rubocop can also enforce an "outdent"
style.  However, it seems that the overwhelming majority of access
modifiers already in the code use the indented style.
Fix the few access modifiers that were outdented
Rubocop: allow TrailingBlankLines enforcement
Clean up trailing blank lines
Rubocop: allow StringLiterals enforcement
Change double-quoted string literals to single-quoted where possible
Tighten up block nesting levels allowed to 6 max
Exclude some Builder code from Rubocop checks

These tend to inflate the length of classes and methods,
running afoul of the ClassLength and MethodLength cops.

Align parameter lists spanning multiple lines
Rubocop: allow EmptyLines enforcement
Clean up extra blank lines
Break up some overlong comment lines
Rubocop: allow BracesAroundHashParameters enforcement
