Add Haskell solution to problem 2
Add Haskell solution to problem 1
Add README
Scheme solution to problem #1

This can be much more elegant, but that will take some time away and
some mulling over.
Implement sum with foldl
Use correct terminology (multiple) in solution 1
Add Java solution to problem 1
Scheme solution to problem 2

This too can be much more elegant, but it will take some thought and
some added experience with the language.
Java solution to problem 2
Some directory reorganization
Reorganize Makefiles and correctly ignore binaries
Add progress towards Haskell solution to problem 3
Ignore notes-to-self
For prime numbers, return self as GPF
Update Haskell #3 to be sufficiently efficient
Haskell #3: Add type declaration to factors
Haskell #3: Code cleanup (names, whitespace, etc.)
Haskell #3: Include squares in list of factors
Haskell #4: Solution
Haskell #5: Solution (brute-force)
