How to Use This Package:

To install the stable version of GBpy:
```
$ pip install GBpy
```
To install the development version of GBpy Clone the repository:
```
$ git clone https://github.com/adehgha/GBpy.git
```
and run the setup script.
```
$ python setup.py install
```
Import the package:
```
>>> import GBpy
```
Call the function by using:
```
>>> GBpy.<name_of_the_function>
```
- for example to find the 2D basis vectors of a plane with Miller indices of (h,k,l):
```
>>> GBpy.bp_basis.bp_basis([h,k,l])
```
You can also use the tools provided in this package individually by importing the functions separately. For example use :from GBpy import <name_of_the_function> as <a_name>.
