* use tcc for FORTRAN77 and INTERCAL.

It works much faster and with less memory than gcc.
I believe that this fixes #2 and fixes #7.
* the Ada source file name should be lower case.

I really hate languages that restrict file name...
* delete lower case qr.* when rake clean
* enjoyed Forth programming.

Now, Forth program encodes FORTRAN77 and Fortran90 instead of
CoffeeScript.
The modularity was improved.  The code size was reduced.
* refactoring for image generation.
