terrautils/geostreams.py: document EPSG:4326 coordinate system requirement

[Chris-Schnaufer]

Tags: EPSG, Coordinate System, Spatial Reference

Description

The code in geostreams.py assumes EPSG:4326 coordinate system. This could lead to problems if other coordinate systems are used

Details

Right now a coordinate system of EPSG:4326 is assumed, but this isn't documented anywhere. Documenting this requirement will give developers an opportunity to perform conversions

Completion Criteria

• the requirement is documented in all appropriate places
