Added a new package for data analysis and scientific visualisation.

Hello,

Thanks for maintaining this beautiful package manager!! +++++

I added a new package for data analysis and scientific visualisation which i like a lot because it's an open source version of a proprietary application Origin lab. The application name is qtiplot.

To install this software some dependencies were necessary:
1) Liborigin2 which is the main statistical library
2) tamuanova which is a small library to compute ANOVA analysis 
3) alglib to compute some sparse matrix operation and is needed for qtiplot

However the actual qtiplot suffer of a bug. The actual version of muparser it is not working, and there is still a bug opened here > http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1122549.html

So the version needed to be working is the 2.2.0  which is not in the actual repository.

Finally to avoid problem, i linked statically the qt-assistant-compat 4.6.3 (which was removed from qt >= 4.7).

I'm waiting your answer to know if this application will be integrated or not in the official homebrew git repository.

Best regards.
