 *  https://github.com/jeka-kiselyov/mdict
 *  Very rude refactoring of https://github.com/fengdh/mdict-js to make it work with node.js by Jeka Kiselyov ( https://github.com/jeka-kiselyov ).
 *  Done enough to make it work for my project(with predefined dictionaries). Though tested with few .mdx files only. 
 *  There may be some bugs for other dictionaries. Please check.
 *  Please feel free to post pull requests with optimizations, unit tests etc.
