Defined a new set of APIs and data types for constructing an infix operator parse table. Re-wrote some of the parsers in the "Dao.Object.NewParser" module to take advantage of the new APIs.
I am using a tags file now, generated by GHCi, but I don't want to commit this tags file the Git repository (at least not for now), so I am excluding it via the ".gitignore" file.
Made two slight modifications to the Abstract Syntax Tree. (1) Array subscripts in brackets can now be a comma-separated list of indexes. (2) Function calls are now made to object expressions which should typically be expressions that evaluate to a 'Dao.Object.Reference' value, which makes it possible to call a function of this form "a.b.c()".
