make.soapgrid

This routine simply creates a grid of knots (in the correct format) to be
used as in the "internal" part of the soap film smoother

Density surface modelling of line transect data. A Generalized
Additive Model-based approach is used to calculate spatially-explicit estimates
of animal abundance from distance sampling (also presence/absence and strip
transect) data. Several utility functions are provided for model checking,
plotting and variance estimation.
