Adding a new language

add a etc/config/language.defaults.properties file
add a etc/config/language.local.properties file with the first compiler
- make sure the path is correct, and pay attention if CE agrees with you
add language to lib/languages.js
- start with the basics, class LanguageCompiler extends BaseCompiler and implement the OptionsForFilter method
- test the command line options outside of CE
- Comment out the line saying "fs.remove(result.dirPath);" in base-compiler.js, so the latest CE compile attempt remains on disk for you to review
- if the compiler has problems taking different paths, override the runCompiler method and add a customCwd parameter to execOptions
- test with node app.js --debug so you see all execution arguments and outputs
add a basic lib/compilers/language.js (and reference to it in etc/config/language.defaults.properties as the compilerType)
you can check http://127.0.0.1:10240/api/compilers to be sure your language and compiler are there
