Added calculation to model.
Got calculation working with current code.
Fixed issue in computation form where remove buttons would disappear on validation error.
Updated computation scheduling code. IDs added, now submits after Computation created, and result links (wms, nc, opendap) are fields in a Computation. Still needs to be tested
class for status response codes
merge
Computation status now stored as object,  and also retrieved from resulting zoo xml file. Scheduling the computation in zoo is also now done automatically after each computation is created
Updated ajax code to update status - now takes status code
Added check for number of datafiles in form.
Moved check for number of datafiles in form to view.
Merge branch 'master' into climateanalyser
Moved check for data files back to form, but this time use self.data instead of request object so the code is can be used by admin backend. This is the correct and awesome way of doing it, woohoo!
Updated ComputationForm javascript so that when adding a new data
file, the URL will default to '----'.
Added variables to computation schedule request
Working on check to see if existing result already exists. Rough
and still untested. Need to also filter for calculation!
Fixed bug in ZooAdapter with regexes on result links.
Finished check for Computations with the same data.
Added check in check_for_existing_reuslt function to make sure
that we look for the Computation with up-to-date results.
Removed deprecated reference to DataFile.last_modified
Update so that if Zoo sets a Computation's status to 'success',
the completed_date of that status will get updated!
