Now generates for all files that have been imported. CGenerator uses this to generate all files AND a shell script with the compile command to compile the generated C file.

Can import other files now. (in same directory, use filename without .krak file extention) Right now, still need to compile both files with kraken.

Added caching of the RNGLR table. It is automatically regenerated whenever the grammer changes. Right now it has dropped compiling the test file from 30 seconds to less than one second.

Added generator-dependent compilation and simple passthrough that allows us to have non-cheated emitted, printing c-code for the first time! (no typechecking or anything yet, but we'll get there). It's also still rough.

Small fixes to the grammer, ASTTransformation and CGenerator. Should now be ready to begin implementation of multiple files, conditional inclusion, and code passthrough.

FINALLY fixed an error that took weeks. Turned out that the ParseRule was shallow copied, and the lookahead was not copied correctly. So it got extended and thus skipped over the state when it should have been redone.

Use std::string::substr() instead of adding one character at a time. This patch also removes a few unused util functions that are easily written using substr().

Replace some code in StringReader::getTokens() with std::string::find_first_of(). Since this makes found_pos unsigned, a few comparisons involving found_pos must be adjusted (unsigned integers are always >= 0).

Have a nullableParts generator now. It works for simple cases and may work for advanced cases, but more testing is required to ensure full usability.

Started adding the nullable parts machinery. Also started to fix addStates for RNGLR and null reductions so it only truncated the rule to what had already been parsed, but now it looks like it maybe shouldn't truncate at all and use pointer position for length. However, I have to go to bed and will pick up later.

The out of orderness was actually the fault of the dot graphing program, not Kraken, so that's good news. DOT generation has also been modified so that it properly inserts \n's (actually \n's) where line returns are so that dot can parse the \n and not the line return.

Lexer/RegExs now work on a very basic level. Regular expressions have not been fully implemented, but the structure is there. It creates trivial regexs that only accept a specified sequence, no actual regular expression power.
