> Sometimes it is necessary to process a product directory only when the directory has
been fully produced, or transferred, which can be indicated by the existence of a special
"marker file". It is suggested that we implement a precondition that checks for the existence
of a given file within a given product. This precondition would be implemented similarly to
org.apache.oodt.cas.metadata.preconditions.ExistanceCheckComparator, but would check for a
file at location: 
> File file = new File(product.getAbsolutePath()+"/"+filePath);
