fix error message format for d-to-c translator
fix operator '?' so values returned are checked for correctness

If a user defines a new class X and defines a new comparison
operation method function for X?X, it should return one of the
following symbols: <, >, ==, incomparable.  This is now enforced,
to prevent confusion, in that an error message signals an incorrect
return value.
fix the documentation of the comparison operator x?y
adjust .gitignore files
amend the INSTALL file
add a helpful error message
