Creates a Mapping from a file.
Each line in the file results in a SingleMapping (unless it begins in #, in which case it either indicates the name of the mapping or is a comment).
Within a single line, the first white-space delimited token represents the name of the class, and the other tokens are attribute values.
Any parse failure in the file will stop the entire Mapping-creation process and result in NULL being returned.
corpus | The corpus for which the Mapping is valid (pointer). |
attr_name | String naming the attribute for which the mapping is valid. |
file_name | The filename of the map spec. |
error_string | A char * (not char[]), which is set to an error string, or to NULL if all is OK. |
