Qtiplot: a cross platform data analysis and scientific visualisation solution

Hello,

i would like add qtiplot package to homebrew-science because it's an excellent solution to the data visualisation and data analysis compared to its commercial version "OriginLab". This software need qt-assistant-client which i submitted to homebrew waiting to get the answer if the package will be merged or not. Othe dependencies are in this branch. 

Thanks for your answer.

Best regards.

Marco
