Udpdate module names to new convention.

[ilopezgp]

Updates module names to follow the convention of module having the same name as the file where it is stored.

Also eliminates the EnsembleKalmanProcess module and structures the EnsembleKalmanProcess tests.

[odunbar]

So to summarize we changed some modules. So that a module ObjectNames contains a struct ObjectName

• Removed EnsembleKalmanProcessModule completely, now only refer to the parent module EnsembleKalmanProcesses.
• Renamed ParameterDistributionStorageto ParameterDistributions.

Did you also want to change the following?

• DataStorage to DataContainers (as module creates the DataContainer struct)
• Obs to Observation (as it is contained in the module Observations)
  (This would require filename changes too)

Good suggestions, I will do that as well.
