tc_mfunc(
  chrono,
  climate,
  boot,
  sb,
  start_last,
  win_size,
  win_offset,
  ci,
  method
)

`chrono`	tree-ring chronology
`climate`	data.frame with climate parameters
`boot`	which bootstrapping method should be used? (or "none")
`sb`	logical: draw statusbar or not?
`start_last`	logical: start with last (oldest) window?
`win_size`	numeric: size of the moving windows in years
`win_offset`	numeric: size of offset between moving windows in years
`ci`	numeric: p-level for confidence interval (must be in c(0.1, 0.05, 0.01)
`method`	character: method to be used (one of "response" or "correlation")
`p`	probability for rgeom, that determines distribution of sampling blocks for stationary bootstrap scheme
