Get a list of Instrument objects. Instruments have a 1:1 mapping with Observations.

### Available end points:

- `/instruments/` - Will list all Instruments in the database
- `/instruments.json` - Will return all Instruments in json format
- `/instruments/<object_id>/` - Returns Instruments object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `title`
- `uuid`
- `keywords`
- `instrumentType`

### How to use filters:

- `/instruments/?title__startwith!=Instrument.title: DETAILS NEEDED`
- `/instruments/?uuid=c7fa005e2095425392b18adbd7b40617`
- `/instruments.json?instrumentType=radiometer`

    "abstract": "The Condensation Particle Counter (CPC) is a GRIMM CPC 5.400. The CPC is located on the roof of the MSF building at Summit station, 72.578590N -38.452693E, approximately 3 m from the ground (depending on snow drifting/ accumulation).  Inlet losses are < 15% for particle sizes 0.08 to 1 μm diameter. Inlet losses are > 50 % for particles smaller than 0.02 μm and larger than 2.2 μm diameter. \r\n\r\nThese data were collected as part of the joint Natural Environmental Research Council (NERC) and US National Science Foundation (NSF) -funded Integrated Characterisation of Energy, Clouds, Atmospheric state, and Precipitation at Summit - Aerosol Cloud Experiment (ICECAPS-ACE) project.",
