Implemented various optimisations of the 0.2.0 version, including different filtering and rewriting approaches for model enumerations
* ADD prefilter for stable model computation (hybrid and naive)
* ADD implementation with one big rewritten formula instead of many
* ADD second version of bdd rewriting method
* FIX documentation, UPD flake
* UPD Readme, usage
* ADD hybrid options for grounded and transformation
State of the art BDD library, naive implementation, and Hybrid-approach available in the first beta-release version 0.2.0
* ADD biodivine as an obdd library to adf-obdd
* Implement restrict-wrapper on Biodivine
* Testcases changed to use biodivine for grounded.
* API unified
* ADD stable and complete with biodivine
* moved main.rs to bin folder
* ADD biodivine -> naive translation
* ADD hybrid approach
instantiation + grounded by biodivine, then naive approach with memoization
* TIDY Readme, doc, tests
A couple of bugs have been identified, where the complete interpretation either identified too many interpretations as being complete (bug in complete_iter) or too less interpretations (bug in ThreeValuedInterpretationsIterator)
They are fixed now
Implements #12
* Implement Stable Models based on lazy evaluated iterators
* Adjustment of the internal computation of the grounded interpretation
* Update build.rs to replace "@" in test-instance names with "at"
* Implement de-/serialization of the adf (in OBDD representation) in library
* Adjust tests
* Add more style-restrictions to compiler
* Implemented a nom-based parser to read the adf
* Grounded semantics (naive) re-implemented
* Docs added
* Updated Cargo.toml with more Manifest information
* Version update
* Added sort-methods to the parser, so the var-order can be adjusted
* Added sort functionality to the main function
* Added adf-instances as a submodule to the res-folder
* Added README information for the extended integration tests
* Rewritten main-function
Closes#3
