Modules generation tool (#81)

Browse source 
* Modules generation tool

* apply clang format to generator

* @whereismyfoodat suggestions

* added reuse headers

* reuse part2

* reuse part3

* reuse part3

* replace with hex_id the unknown functions to avoid compile errors with unknown characters from encode_id

* fixes in generation

* some sample module code from autogen tool

* clang format fix
