Creating an extensive test suite.

[mmzx]

Creating an extensive test suite, so we could add syntactical extensions. Keeping compatibility is of high priority.

I'm just learning Haskell so y'all would have to be patient with me ... but I'm willing to work on this were needed so that changes could be introduced faster.

Any advice, blogs, books etc. would be great

Perhaps golden testing may fit the project?

Also, moving as much as possible (including the conversion from ER to Graphviz) from the executable to the library (from app/ to src/) could ease the testing (see also #10).
