Driver

• Removed bash-based driver
• Added new java-based driver
• Added tests and unit-tests coverage for the driver

OMNI compiler

• submodule now pointing to
  omni-compiler/xcodeml-tools@0276bc0
• Switched to CMake based build
• Switched to C++ version of frontend (i.e. ffront-cpp instead of F_Front)
• Added CMake option BUILD_OMNI_XCODEML_TOOLS to use pre-installed OMNI (when set to OFF)
• Added CMake option OMNI_LINK_STATIC_GNU_LIBSTDCXX to build OMNI with static libstdc++ library
• Added CLI option --ffront-debug-dir to the CLAW driver for replicating failed calls to OMNI

Other

• updated install and developer documentation
• updated sonar to new version
• updated coding style

Release v2.0.2 + preprocessor fix.

• OMNI Compiler submodule now pointing to omni-compiler/xcodeml-tools@3bbc8ec
• Added support for NAG compiler
• Various bug fixes

• Serialization is now disabled by default.
• Driver: Add option sca_forward_update_disabled to switch globally updates.
• Driver: Add option sca_forward_update_direction to fine tuned updates.
• Driver: Add option sca_serialization_enabled_direction to fine tuned serialization.
• SCA: fix inserted module use in automatic serialization when serialization is disabled.

• array-transform directive as been renamed expand as specified in v2.0 of
  the CLAW Directive Language Specification.
• parallel clause for expand directive is implemented.
• update clause for expand directive is implemented.
• beta serialization support for expand and sca elemental directives.
  • Support Serialbox 2 at the moment (https://github.com/eth-cscs/serialbox2)
• SCA: support for transformation in ELEMENTAL function/subroutine for
  GPU target
• low-level: block directive like loop-hoist can now be nested on the same
  depth.
• driver: _CRAYFTN macro is passed directly when Cray preprocessor is used.
• OMNI Compiler submodule now pointing to
  omni-compiler/xcodeml-tools@772cf79
• Java 1.8 or newer is now required for CX2T.

• driver: fix preprocessor filename for Cray in dependency resolver

• driver: fix temporary file name being too long in some cases.

• driver: new option --add-paren to force parenthesis on mathematical binary
  operation in code generation.
• driver: fix automatic dependency resolver arguments passing (#478)

• SCA: Support model configuration file with the --model-config=<path> option.
• SCA: parallelize can still be used but it is deprecated. Use the new
  !$claw sca directive construct.
• SCA: in directive dimension definition is still supported as a local model
  configuration per pragma.
• SCA: Support model-data directive.
• Various bug fixes.
• OMNI Compiler submodule now pointing to
  omni-compiler/xcodeml-tools@4f66174
• Current version of OMNI Compiler can fully parse/validate COSMO CPU/GPU.
