prep encontrar for piping
* instead of appending results to a txt file, we can pipe the output of the
script into a node script that'll generate the html we want
mostrar - display all the hexes you're using
* currently accepts piped input from encontrar
* would like to investigate a way to put a fiter on the piped input,
instead of having to de duplicate in the createHexObjects function
generate html file of hexes
* refactor egrep to use -o flag for matching
