public class DataFilePaths
Simple utility class: reads the environment variable in
ENV_VARIABLE and provides a method that converts strings which
start with that environment variable to file paths. For example,
you can send it
and it will convert that to
unless you have set $NLP_DATA_HOME to something else.
The only environment variable expanded is that defined by
ENV_VARIABLE, and the only place in the string it is expanded is at
the start of the string.
