v0.4.0

Major changes

• (^Context) pass and (^Context) fail now return a boolean to pass to (^Context) endCustom
• Added new assertion function (^Context) assert.sameType
• The library now exits with a fatal error if:
  • a custom assertion function does not end all of its branches with T.endCustom
  • a previous assertion function failed and its enclosing function did not return

Minor changes

• Hid implementation fields funcDepth and customAsserts
• Rearranged elements around the library into a more pleasing order
