Bug fix: NaN caused error when plotting a 3D graph.
Bug fix: some sequence of data still caused a broken EPS.
When you drop a .mjo file, it is now properly opened as the mjo file instead of importing it as a new series.
Updated the latex compilation script to work well with Ghostscript 9.
Implemented 3D plot.
The decimal point character is explicitly set to the "." (period) instead of "," (comma) for the countries where the default setting is the latter (like Germany, Brazil, etc.).

Bug fix: Loding .mjo file failed in Matlab.
In Matlab, the number of rows readable at one time is limited in order not to run out of memory.
You can now control the number of tick marks in a decade even when the axis scale is set to log.
Modified csv file reading algorithm for robustness as well as efficiency.
This version can run on Leopard.
Column pair to be plotted can now be designated as you like.
