Create folder structure appropriate for testing

[Sword-Smith]

Troels: Can you make a folder structure which is appropriate for testing? I would like to run unit tests on various function in the different modules located in src/ but when I create test modules in T/, I cannot get those modules to import the modules found in src/

[Sword-Smith]

On a clear install of this program using stack, I wrote a test module in T/RegAllocTest.hs and executed ghci T/RegAllocTest.hs from both the root folder and from the T/ folder. This resulted in the following error message:

GHCi, version 7.10.3: http://www.haskell.org/ghc/  :? for help

T/RegAllocTest.hs:3:8:
    Could not find module ‘MipsRegAlloc’
    Use -v to see a list of the files searched for.

T/RegAllocTest.hs:4:8:
    Could not find module ‘Mips’
    Use -v to see a list of the files searched for.
Failed, modules loaded: none.

I was able to fix the importation of modules located in src/ to files located in T/. This was fixed by adding a .ghci file in the root folder containing the text

:set -isrc

Is this the correct way to handle this or should stack somehow be used?

The right way is to use Cabal's support for test suites. I'll create a skeleton.

(I'll also do something more interesting soon.)
