Advent of Code - Smalltalk Edition

Warning: I am in the process of learning smalltalk - style and appropriate idioms may not be properly followed, although I welcome issues that highlight my mistakes :)

To run examples the following files are required:

• For AdventFileReader.sm create a category AdventHelpers and add the class AdventFileReader
  • The readLines function is a class function.

At this point you should be able to:

• copy-paste any of the specific day / part files into a Workspace window
• select all (Ctrl-A)
• print the result (Ctrl-P)
