made default number of reps 2000
added get.fn based on hadley's SO response (see comments for link)
added more comments
use get.fn to get bootstrap fn
use get.fn to grab estimator function
srs.bootstrap.sample now has ... arg instead of unused named args
cleaned up comments in bootstrap.estimates
rbs now works with 0 or more than 1 psu var...
updated comments to reflect last commit's changes...
changed order of args so num.reps is second
bootstrap.estimates now handles all fn args the same way, using get.fn
get.fn now returns its arg if already a fn; also cleaned up docs

minor changes
now there are two fns, one for each rds bootstrap method (markov chain based and static chain based). i believe both are now working
