Concero

Added

* Experimental support for *exporting* into GDX data files (alongside experimental import support).
* Improved error messages for incorrectly specified `orientation` and `usecols`.

Changed

* `matplotlib`, `pyqt4` are now imported as needed, removing PyQt4 as a strict dependency for ConCERO.

Added

* Added pip-compatible changes.

Added

* Experimental support for *importing* VEDA data files (no export support yet).
* Experimental support for *importing* GDX data files (no export support yet).
* Anaconda environment file to simplify install process.
* `-v`/`--version` option for printing program version.
* Date and time is now printed at completion of model execution.
* Tests of ``__main__``.
* Added tests and documentation of `init`, `init_cols`, `init_icols`, `auto_init` and corresponding post keyword arguments of wrapper functions.

Changed

* Minimum python requirement increased to `3.5`.
* Minimum pandas requirement increased to `0.23`.

Changed
* (BACKWARDS INCOMPATIBLE) Command-line interface for ``concero`` has been changed to enable data format conversion operations (without model executions) from the command line. A ``Scenario`` defined in a YAML file is now run like:

concero run scenario_file.yaml

And data format conversion can be accomplished by running the command:

concero convert import_def.yaml export_def.yaml

Or (more simply):

concero co import_def.yaml export_def.yaml

* Removed requirement for procedures to have a specified `name`. `name` will be `"Unnamed_proc"` by default. Documentation has been updated to reflect this.
* Removed requirements for models to have a specified `name` and ``cmds`` (and updated documentation to reflect this). A default name is given if none is provided.
* Removed the requirement for scenarios to have a specified ``name`` (a default ``name`` is given instead). Documentation updated to reflect this.
