The Process in Brief

1. Enter the mapping placeholders into the mapping file.
2. A call to initMappings() should then be made, passing the name (and path if necessary) of the mapping file. This will then return a Vector of the placeholders that were contained within the mapping file.
3. parseDocument() can then be called, passing the name of the template file, actual data¹, and mapping entries.

It's possible that the path and name of the merged file may need to be specified. These have default values, however, if your platform in not a Unix based system then the path will have to be specified as it defaults to '/tmp'.
