paida-3.2.1_2.9 released

[3.2.1_2.9] (AIDA3.2.1_PAIDA2.9)

### New features ###

- Simple matrix calculation
- 3D rotated plot
- Chi2 fitting with asymmetric weight
- Tick line controll
- Improved IPython support (And both Tcl/Tk and Tkinter should be configured with pthread-enabled if you use Tkinter plotting engine.)

### Bug fixes ###

- scale() didn't calculate errors correctly.

paida-3.2.1_2.8 released

PAIDA is pure Python scientific analysis package and implements AIDA (Abstract Interfaces for Data Analysis).
The main features are:

- Pure Python!
- Creating/Plotting the histogram, ntuple, profile and cloud
- Fitting parameter optimization with constraints and its parabolic and asymmetric error evaluation

[3.2.1_2.8] (AIDA3.2.1_PAIDA2.8)

### New features ###

- Now PAIDA works on JAVA with Jython2.1 (Python in JAVA).
- of course still works with Python.
- uses Swing for the GUI engine.
- Now you can use large number of extension libraries of not only Python but also Java.
- Improved IFitter.
- New fitting engine "GA" and "SimpleGA" are available. They use "Genetic Algorithm" and is very slow but strong.
- "PAIDA" and "SimplePAIDA" fitting engines got more optimized speed.
- Support for 'dot', 'dash', 'dash-dot' and 'dash-dot-dot' line type in addition to 'solid'.

paida-3.2.1_2.1 released

PAIDA is pure Python implementation of AIDA (Abstract Interfaces for Data Analysis -> http://aida.freehep.org/ ).
PAIDA can create/plot/save/load histograms, clouds, profiles, functions, ntuples.
The parameter optimization and its parabolic/asymmetric error evaluation are also supported.

In this release, there are some limitations yet but almost all analyses can be done.
