v0.3.2

User Facing Changes

• Lambda Changes
  • Added an error node so that users can express failure
    • This is translated into a maybe type internally for now, and
      affects the compilation downwards.

Bug Fixes

• Gapply (the interpreter) now works correctly for the BITC in the
  SWAP case.
• Fix an issue where higher order functions in the Lambda frontend
  would generate incorrect logic when extracting to the core category

Internal

• The pipeline extractor now properly takes the input stream given to it
• The Vamp-IR extractor function now properly accepts null streams

Internal Changes

• A maybe function now exists generically throughout the codebase,
  allowing one to maybe any object type. See Maybe in the Generics
  section of the documentation.
