## Technical Description

Provides (de)serialization capabilities to json files. 

## Testing

Was tested with the set of stencils provided in the code gen tests in the sense that code gen from DSL and codegen with an intermediary serialization and de-serialization step produce the same code. Proper testing for (de)serilization and using (de)serialization to test the code gen will be introduced in a separate PR.  

## Dependencies

Depends on [Pull Request 236](https://github.com/MeteoSwiss-APN/dawn/pull/236) in the dawn repo

* Update namespace prefixes

To update to dawn's new namespace organization. AST nodes and utils needed are now in namespace dawn::sir

* Add dawn PR dependency

* Update on changed BoundaryConditionDeclStmt

* Update on StencilCall moved to AST

* Fix include

* Pointing dawn repo back to master

* Point to dawn PR

* Point to dawn PR

* Fix mistake in include

* Change bundle ref to dawn back

## Technical Description

This fixes the issues with the namespaces used in generated code. Namespaces like "cuda" or "gridtools" should be used only by cuda and gridtools themselves. The generated namespace is now nested and the gridtools namespace has been renamed to the shorthand gt. 
```
namespace dawn_generated {
   namespace (cxxnaive|dawn|gt)_generated {
      //stencil code
```

Compatibility for clang up to 8.0

This fixes the path in GTClang since we moved a piece of code to a different module

Changes the usage of halo values to be more consistent and puts less burden on the user.

Update the printStorage function to not loop over the full k-domain but the k-domain that is specified by the storage.

Update to clang-format 6.0 and a reformatting of the repo

Field versioning will be 0-based, hence reference files need to be updated

* Fix tests failing due to new json dump format

Fixing integration tests of before/after StageMerger and StageReordering passes failing due to the change of the json dump format

* Fix tests failing due to new json dump format

Fixing integration tests of before/after StageMerger and StageReordering passes failing due to the change of the json dump format

* fix wrong branch name

wrong branch name put in CMakeLists.txt referencing dawn PR

* restored dawn master dependency

The build-stage still had the deprecated maintainer keyword in it. This is just cleanup for the sake of consistency.

Removes output files from the parsing unittests, The tests still compare the SIR's but are no longer polluting the output with files / text.

This moves the jenkins execution planes to the correct group

Removes the diagnostics check of checking for uninitialized temporaries. This was previously enabled but the pass needed to be disabled due to its buggyness. 

This allows for std::cout as the output rather than a generated file which make the use of containers much simpler.

They are correct but are potentially false positives as ordering matters

* renaming

* removal of the semicolons where needed

* serializer that appends code
