comparison parser/Action.d @ 172:01c2c49775ef

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
- Changed Parser to be more clean on type parsing. - Parsing int function(int), and the like, types.(Function pointers) - Fixed a design fault that made Symbol be wrong. Now Symbols are created with a factory with the help of types.
