Spellcheck code challenge

To get started, first install the node dependencies. I used yarn for my package manager:

yarn install

Then, to run the spellcheck program against your input file, run:

yarn start {path/to/dictionary.txt} {path/to/input-file.txt}

• The core spellchecking logic all resides in the spellcheck.ts file and its associated functions. The index.ts file only handles parsing the input files and printing out the results.
