TGCS: TDL Grammars in C-Sharp

A project to develop a system for processing DELPH-IN style TDL grammars within the .NET and Mono runtime environments. So far, the system is able to do the following:

• Robustly tokenize TDL and read in grammars, providing precise indication of syntax errors;
• Build the type system and efficiently calculate the greatest lower bound closure;
• Unify types to compute minimal inference for the authored type hierarchy;
• Load feature structures into an internal representation that is hoped to support efficient DAG unification;
• Display feature structures in a embryonic style inspired by LUI.
