onavdata 0.0.3

Quickly import reference data sets for navigation system design and testing.

# Organic Navigation Reference Data

The purpose of the `onvadata` module is to make reference data sets easily accessible for the design, development, and testing of navigation algorithms. The defining characteristic of reference data sets are that they are well understood, documented, and purged of data logging artifacts.

## Quick Start

### List Data Available
All data sets are referenced using their shortname.
```python
>> import onavdata
>> onavdata.print_shortnames()
2011 UMN-UAV GPSFASER1
2012 UMN-UAV FASER5
2012 UMN-UAV GPSFASER3
2012 UMN-UAV THOR79
2012 UMN-UAV THOR77
2012 UMN-UAV THOR75
2012 UMN-UAV THOR60
```

### Load a Reference Data Set
An abitrary data set can be loaded if no shortname is specified. In this case the data from `2014 UMN-UAV THOR77` was returned.
```python
>> import onavdata
>> df = onavdata.get_data()
get_data(): No shortname specified so choice will be arbitrary. Returning: 2014 UMN-UAV THOR77
>> df.head()
AccelX (m/s^2) AccelY (m/s^2) AccelZ (m/s^2) ... AngleHeading (rad) AnglePitch (rad) AngleRoll (rad)
TimeFromStart (s) ...
