/**
* Makes a copy of a vertex neighbour list file with only vertices in given list. Reads in a file
* (typically an vertex neighbour list) and outputs a copy except for any lines whose first entry
* is not in given vertex list.
*
* <p>Each line has entries separated by whitespace. Comment lines are always copied.
*
* @param vertexNameToIndex map from vertex name to an index
* @param fullInputFileName full filename of input file to be copied.
* @param fullOutputFileName full filename of output file
* @param fullOtherInputFileName full filename of second input file needed for synchronisation
* @param cc if, after any white space, first word starts with this string then line is treated as
* a comment line.
* @param sep sepation character, e.g. tab
* @param vertexColumnList list of columns to be compared
* @param convertToIndex convert the vertex names to an index as given by the map provided
* @param forceLowerCase force all strings to be lower case
* @param infoOn true if want more info printed out
