Try to format the README.md correctly.
markdown again...
Start a clean TODO file (there is a lot of things to do, this file will be precious :)).
Add a small GPL header.
Add 2 submodules: posn-on-screen and popup-frame (in order to start a completion frame).
Try `el` code block for syntax highlighting.
Handle the kind (for example the completion is a destructor) of the completion results.

Now the 'simple' completion is handle on the C++ side.
Use cmake instead of plain old Makefiles (also change some "coding conventions").
Fix compilation error and build instructions.
"Fix" README.
Fix potential infinite loop that block Emacs forever.
Move the completion stuff (elisp) in a dedicated file.
New TODO.
Add auto-completion for #include directives.
Oups, forgot to commit change to irony.el necessary to the previous commit (9e3f5bf).
Start a very small documentation on how to set a working project with irony-mode.
Update README.md (comment for Mac OS X compilation of SimpleJSON).
Fix compilation errors and warnings.
Add NOT-really fonctionnal syntax checking capabilities (WIP).
Suppress the unused ":category" field in syntax checking.

A change in clang-c/Index.h deprecate the function
clang_getDiagnosticCategoryName(...) (since clang 3.1 I think). And
the category is not really important for the moment.
