Metacat

try to read the local document before making the localid->guid mapping (in cases where we fail to read the data locally like if it is referenced in an EML file but does not exist on this Metacat instance)

add note to enable ssl mod

-include instructions about enabling AJP connector in Tomcat config
-use postgres 8.4
-include hint to disable default Apache site (otherwise the knb config never gets used!)

include instructions for installing Sun's Java6 JDK since it is no longer in apt-get repos

Ensure we have the object and sysmeta params for MN.create(). We were getting a fatal SAX parsing error encapsulated in a ServiceFailure when a science metadata object param was null. Cut it off at the pass after parsing the MMP entity.

An example python script that uses the python client to loop through a list of
files, read them from disk, and insert them into metacat.

make it clear that the Apache config files are samples and may need to be modified for different servers

update system requirements to be more reasonable

use larger ("text") db field for guid in the xml_access.accessfileid column

use EML 2.1.1 tag as final tag for the schema
