Parse c++ files and create a relational database with all the identifier present in the code.

Example:

jd@desktop:~/$ cppa -f ~/c++/cppa/cppa/test/ -r -d test.db
/home/jd/c++/cppa/cppa/test/test1.cpp
/home/jd/c++/cppa/cppa/test/var_decl.cpp
warning: /home/jd/c++/cppa/cppa/test/var_decl.cpp(16): warning: last line of file ends without a newline
/home/jd/c++/cppa/cppa/test/a folder/another one/and another one/test2.cpp
