dependencies: cmake, python, clang, emscripten, node

1. create a build directory somewhere
2. inside this directory call cmake <CMakeLists.txt directory> and make
   (the CMakeLists.txt file is located in <uncrustify_root_dir>/emscripten)

Optionally the generated libUncrustify.js can be tested via make emscripten_test

1. load module instance:

   var uncrustify = libUncrustify();

2. set option settings either one at a time with:

   uncrustify.set_option( "optionNameString", "newOptionValueString" );

   or a whole bunch via:

   uncrustify.loadConfig( "configFileFormatString" )

3. set the language of the to be formated file string

   uncrustify.set_language( languageInt );

4. format a file string:

   var uncrustyFileString = uncrustify.uncrustify( "crustyFileString" );

5. delete initialized module instance:

   uncrustify.destruct();
