wxMathPlot 0.1.1 Released

This is a minor, but nice version: it introduces a new feature, the sohw/hide for single plot layers. This allows to give finer control of visualization. This is also the first release packaged as RPM, enbling to easily install wxMathPlot on rpm-based Linux distributions. They have been tested on Fedora 10 and Centos 5.1, but I believe they should work also on other distributions like Red Hat, SuSE or Mandriva. Let me know... A big thank to all the contributors and users who sent patches, new features and bug reports.
