Diffing of (expression) trees.

Examples

tree-diff displays pretty diffs of tree data:

Because of its untyped internal type, it copes with type changes:

As a bonus, multiline Strings and Text are diffed linewise:

Breaking change: Make HashSet and HashMap ToExpr instances sort the resulting lists of expressions. This makes the results deterministic. … but your golden files will need adjustment. https://github.com/haskellari/tree-diff/issues/67
Add Ord Expr and Ord OMap instances
Depend on data-array-byte to provide more ByteArray instances

Change the pretty printing to use less horizontal space. Pretty datastructure is changed.
Change Expr to use OMap; pretty-printing preserves field order.
Add strict and these instances
Add Eq and NFData (Edit a) instances.
Bump lower bounds

Support GHC-7.4 … 8.8 (use allow-newer for GHC-8.8-alpha).
Use raw GHC.Generics (drop generics-sop dependency)
Use own memoising (Vector lookup, drop MemoTrie dependency)
Singleton data-types (both data and newtypes) are printed in App form (i.e. no-record).
Change license to GPL-2.0-or-later

Use BS.readFile and BS.writeFile in ediffGolden. This makes files read and written in UTF8 independently of locale. Fixes builds on appveyor.
