Increase package modularity #74
Description
The package needs restyling to improve modularity and maintenability.
In particular, block.py is way too large and shall be disentangled in:
- config.py dedicated to configuration, hence SMSConfig
- plot.py for plotting
- io.py for input/output
- definitions.py for Block, Variable, Dimension and Attribute definitions
- standard_blocks.py [or equivalent] to read the standard block types
- tools.py for smspp tools. Ideally, the solver registry shall be generalized and extended
modules may be created
