Consider renames

[arcnmx]

• [ ] Consider renaming new_x() to with_x() Should the crate use the more Rusty convention for constructors, for example Properties::with_string("x") vs Properties::new_string("x")?
  • See 'grep -rF 'pub fn new_' src/auto/'` for the relevant instances of this.
• [ ] enum const names like ProxyFeatures::PROXY_FEATURE_BOUND are redundant
• [ ] LibraryErrorEnum should be something like LibraryError or LibraryErrorCode
• [ ] check for other instances of verbose or redundant identifiers
