Add support for the SCA alignment algorithm
Cog currently only supports an ALINE-based word alignment algorithm. Johann-Mattis List outlines an alignment algorithm that uses sound classes similar to those used in the Dolgopolsky cognate identification method. The algorithm is implemented in the software package LingPy. The LingPy library could be integrated into Cog.
