numbertowrittenstring

My version of the "number to written string and back" functions. To run the functions, simply do the following:

1. Open the index.js and enter your language, written string and number at the top of the file.
2. Run the file within your IDE or run node index.js in the root directory.

millions and billions will also work!

-- For now the string-to-number function is not finished yet. --
