Removed MxNumeric and MxFloat because now the sqlalchemy.types base classes support dialects having a class attribute of "supports_native_decimal" indicating native Python Demimal support. Adjusted mssql+mxodbc to use the sqlalchemy.types base classes for Float and Numeric instead of using the base mssql dialect's numeric types.
