Fixed issues with the cplus2asp symbol table (both the internal representation and the version outputted).
Added support for the language BC.
Added the 'computed' sort for compatibility with CCalc external calls implemented in LUA.
Added the '.lua' extension to the list of recognized files associated with the grounder. Files ending in .lua will now skip translation and preprocessing.
Fixed an issue where an exception may be thrown arbitrarily during translation.
Fixed an issue which prevented dynamically instantiating a numerical sort via a number range.
Added full support for LUA calls. Fixed the parser to allow LUA calls with empty parameter lists (or, equivalently, no parameter list).
