This commit modernizes the Assembly Calculus codebase to work with Python 3:
## Python 2 to 3 Migration:
- Replace `xrange` with `range` in: project.py, overlap_sim.py, tests.py, brain_util.py
- Fix print statement syntax: `print "..."` → `print("...")` in overlap_sim.py
- Replace deprecated `dict.iteritems()` with `dict.items()` in simulations.py
## Bug Fixes:
- Fix undefined variable error in brain.py:289 (`from_area` → `from_area_name`)
- Add missing `DET_SIZE = 2` constant to parser.py and recursive_parser.py
## Code Quality:
- Standardize indentation in brain.py (convert tabs to spaces for consistency)
- Fix mixed indentation issues that could cause Python syntax errors
## Current State:
The repository now contains a fully functional Python 3 implementation of the
Assembly Calculus model for computational neuroscience research. All modules
execute without errors:
- brain.py: Core neural assembly simulation framework
- parser.py & recursive_parser.py: Brain-based language parsing models
- simulations.py: Comprehensive simulation library for assembly operations
- Tests and utilities: All supporting modules for research experiments
The codebase implements the theoretical framework from Papadimitriou et al.'s
research on biologically plausible neural computation and language processing.
