Adding conversions from two to three letter codes for Apertium Globe-viewer
Our current filtering program currently ignores two letter codes (because all the points are listed as three letter codes) and therefore doesn't add in all the possible pairs.
For example: There is a pair ("ca", "it"). Since they are two letter codes, this pair is ignored. However, by converting it to three letter codes: ("cat", "ita"), we will be able to add this pair in.
Check for pairs with two letter codes that have a three letter code counterpart that is in the list of points and make sure they are added. For a conversion table of two to three letter codes, look here.
Commit the code as part of trimpairs.py in the Globe-viewer repo.
