DESCRIPTION
Complete Spatial Randomness (CSR) analysis based on a moving window.
This function uses either the Clark and Evans (1954) or Donnelly (1978)
aggregation index for testing of clustering of point patterns.

EXAMPLE
An example for the North Carolina sample dataset:
Compute the CSR for the whole landscape of landclass96 using
class 5 (1000 iteration) using the Clark Evans method:
v.random output=randompoints n=100 zmin=0.0 zmax=0.0
v.to.rast input=randompoints output=randompoints use=val val=1
r.pi.csr.mw input=randompoints keyval=1 n=1000 method=clark_evans output=csr1
The results for the whole landscape is prompted to the console.
Compute the CSR for a defined moving window size of
landclass96 using class 5 (1000 iteration, Clark Evans
method):
r.pi.csr.mw input=randompoints keyval=5 n=1000 method=clark_evans size=7 output=csr1
