Table – Code Type Enumeration

The code enumeration where enumerators were used as table indexes was replaced with a code type C++11 enumeration class.  Code types are only needed for codes that are referenced, for example, special operators (open parentheses, close parentheses, equal, comma, semicolon, and colon), some commands (LET and REM), hidden codes (convert to double or integer), and codes with operands (constant, variable, array, etc.).  Several codes are assigned to the same code type enumerator (for example double, integer, string, non-reference and reference variables).

The code type enumeration was named the same as the old Code enumeration because this makes the code read better where they are used.  The old Code enumeration was moved to the table source file for the temporary alternate code initializer lists and was renamed to Code Index to conflict with the new Code enumeration class.  These enumerators will eventually be removed.  In the rest of the classes, the old enumerators were changed to the new enumerators.

The table entry type member was changed to the code (new code type enumeration).  Table entry initializers were updated with new enumerators.  For most of the entries, this was just the default code type enumerator.  The type access functions were removed from the table entry and token classes, and the code access functions were updated to use the new code member.

A new code to entry map static member was added to the table class.  In the add function, if the code is not the default code type and the code type of the entry is not already in the map, then the pointer to the entry is added to the map for the code type.  The argument of the entry static access functions were changed from an index to a code type enumerator.  An entry access function taking an index is still needed for converting program code back to tokens.

The switch statements on the token type in the translator and tester class routines were updated to switch on code type.  This included the test token type name function, where the names output were also changed to match the code type.  This affected the parser tests output, which were updated accordingly.
