probsel: probsel
In syanco/checkyourself: Simulates a simple agent-based species distribution model

Makes probabalistic selections of a cell based on the mixture of two probability matrices. Not intended to be called directly - used by 'chooseloc'

1	probsel(hab.prob, lambda, move.list, coef.d, coef.r, matsize, ...)

`hab.prob`	matrix, the habitat matrix with cell values representing the habitat-only probabilities (uncorrected for the mixing proportions with distance). Typically the second element of the list returned by simlandscapes.
`lambda`	numeric, the strength of the declining exponental function that controls how "reluctant" the agent is to move large distances. Must be <1.
`move.list`	list, the current 'move.list' being maintained by 'chooseloc'. Used to find the current agent position.
`coef.d`	numeric, the relative weight to give the distance preference.
`coef.r`	numeric, the relative weight to give the habitat preference.
`matsize`	integer, the size in number of cells of one side of the square matrix on which the simulation is being run.
