correction to make.density()
fixed initialize Density class so that it can take in a pre-made density surface grid
Allows transects to be loaded from different shapefiles as specified by the user
get.shapefile.names moved to seperate file
get.sampler.info moved to seperate file
now generates Poisson N from D
Added additional options for different design types
Removed some redundant input
Fixed bug so that it can construct and object from a pre-defined grid
Updated the plot function so it can create a new plot which can rescale the axis
from m to km or vice versa
Removed both the perp.truncation and rad.truncation slots and replaced it with
just a truncation slot.
Removed the adjustment and adj.param arguments
New Class Equal Angle Zigzag Design
New class representing a line transect with random (rather than systematic
allocation of transects)
New Class: Line Transect Parallel Systematic Design
New Class: User specified / created design only to be created from
existing shapefile.
Allows a distribution to be entered for Density
Updated generate.population method to generate from either D or N
Now takes in units relating to the shapefile
Plotting function allows basic transformation on axes from km to m and vice
versa.
single.transect.set argument added
changes to simulation.survey to reflect changed slots in Detectability Class
slight change to plotting function
rad.truncation argument removed
radial.truncation slot removed
moved to its own file
#Removed radial truncation distance now it relies on plus and minus
sampling to determine which animals may be detected around the
border of the sirvey region.
