Description

I created an ExternPreconditionComparator class. I needed one and it seemed like a logical thing to do since there are already several 'Extern'-type classes in the OODT. Here are the details:

New ExternPreconditionComparator class in:
oodt/trunk
/metadata/src/main/java/org/apache/oodt/cas/metadata/preconditions/ExternPreconditionComparator.java

New example external script in:
oodt/trunk /crawler/src/main/resources/extern-scripts/check-data-file-complete.pl

Modify precondition-beans.xml in oodt/trunk /crawler/src/main/resources/ and
oodt/trunk/mvn/archetypes/radix/src/main/resources/archetype-resources/cra
wler/src/main/resources/policy/ to add example precondition beans for the ExternPreconditionComparator class.
