generate_grid

Generate a grid around a longitude and latitude, with a defined square size and step size.

A method to calculate the distance to the climatic tree line
for large data sets of coordinates (World Geodetic System 1984) with
geographical uncertainty. The default thresholds and the treeline definition
is based on Paulsen and Körner (2014) <doi:10.1007/s00035-014-0124-0>, users
are free to decide what climate layers they would like to use.
