xdi-pandas 0.2.0

Read XDI files to Pandas dataframes

# XDI Pandas

This modules lets you parse <a href="https://github.com/XraySpectroscopy/XAS-
Data-Interchange">XDI</a> files into Pandas dataframes.


```python
from xdi_pandas import parse

df = parse('file.chir')
print(df.metadata)
print(df.metadata['Version'])
print(df.metadata['Element']['symbol'])
print(df['fit'])
print(df['residual'])
df2 = parse('file2.lcf')
```
### Fields

XDI Pandas being developed primarily to help generate in batch graphs for
Athena generated files, it supports several Athena extension fields.

Fields are defined and validated in [./xdi-pandas/xdi_types.py] following <a
href="https://github.com/XraySpectroscopy/XAS-Data-
Interchange/blob/master/specification/dictionary.md">the spec</a>.
