DdmDatasetModule First Working Version

The DdmDatasetModule is now working with the grid engine that has been crated
allowing for monitoring using grid tools. When run the DdmDatasetModule now
displays actual information from the grid rather than the place holder info.
DdmDatasetController Changes and Module html changes

Added a Database Handler Class for the DdmDatasetController class to use.
This class is used for all interaction with the database that stores the
information that is related to only this module. The way it is currently
implimented is maybe not the cleanest way to do it but for now it is working.
It currently also extends the Gridsubprocess class and has direct access to
the grid. There might be a better way to impliment this but I was unable to
find one.
Fixed a bug in the html page for the module. Before it was displaying 10 rows
of all the same dataset information. Now it actually displays the 10
different datasets that are retrieved from the controller.
Revision Of DdmDatabaseHandler Class

The DdmDatabaseHandler class has been revised so that now it extends
the DdmDatabaseController class. This allows the reuse of the getMetadata
method that is in the Controller class.
Last Run Time Checking Added

DdmDatasetsController now checks when the last time the run method was called
by write the run time or the run method out to a log file. It then reads from
the log file the last time the run method was called the next time the run
method is executed. If it was executed within a certain amount of time ago,
the run method does nothing. If it was longer than that, then the run method
writes out the current run time and then continues with normal functionality.
One bug currently exists. Last time I ran it there was a permisions error
when trying to write to the log file. Work on this will continue.
Merge of DdmDatasetModule Branch into Blue-Giant

This commit is the merge of DdmDatasetModule branch and Blue-Giant. This
is the first merge of any branches in this repo. Blue-Giant will later be
merged into Master.
