How to Use Mathematica:

1. Quivers.m is a package file which defines all private and public functions

2. Create a notebook file and use following commands to import the package:
	SetDirectory[ NotebookDirectory[] ];
	<< Quiver`；

3. Now you can use functions defined in the package. Use following command to
   find available public functions and variables:
	Names["Quiver`*"]
   use ? to find help for some particular function:
	？PresentData

4. Refer to the "present.nb" files for examples

About python - Howto:

1. Generate quivers:
	python ./quiver_gen.py n e

2. Generate data:
	python ./data_gen.py n e

3. use M2:
	python ./M2Script.py n e

4. Generate presenting data:
	python ./present_gen.py n e

5. now you are ready to use Mathematica to present data
