Clean up of intermediate files of generated Container module

Removed debug print

Fixed simpleBinaryDependencyIncremental test

Notes:
1. compileAndMergeProgramIncremental always removes the last declaration 
   from a module; this is to avoid running the checker when only a 
   trivial change has been made to the (console) input, e.g. evaluate
   another expression as opposed to a declaration that does require a 
   type check.
   
2. Module B compiled in standard fashion (using compileAndLink).

3. The final execute actually executes the result of 
   compileAndMergeProgramIncremental rather than doing yet another 
   compilation.
