New Features for Mx 1.24

Minor Bug fix: In multiple fit, the user could supply options such as RS which were simply ignored in earlier versions (< 1.18). In 1.19 - 1.23 they are not ignored and can cause unpredictable results. Version 1.24 onwards traps this problem and returns an error message warning the user of the failure to use the #group command which is as yet undocumented. It is the beginning of language to allow greater flexibility in changing all sorts of group characteristics during multiple fit. Largely oriented towards the front end development, this feature is not recommended for user experimentation at this time.
