fpzip 1.0.0

Numpy wrapper for fpzip algorithm (P. Lindstrom & M. Isenburg, 2006)

# fpzip

Python C++ bindings for the fpzip algorithm.

```python
import fpzip
import numpy as np

data = np.array(..., dtype=np.float32) # 3d or 4d float or double array
compressed_bytes = fpzip.compress(data, precision=0) # b'...'
data_again = fpzip.decompress(compressed_bytes) # 3d or 4d float or double array
```

## Installation

*Requires C++ compiler.*

`pip` Installation

```bash
pip install fpzip
```

Direct Installation

```bash
$ pip install numpy
$ python setup.py develop
```
