No warning from make.acmap or optimizeMap when maxit is too low

[drserajames]

It might be useful to have a specific warning when the number of iterations is equal to maxit in optimizeMap(map). I don't know if this happens often with the default setting of 1000.

In the code below, I set maxit=1, and got the generic warning about instability.

> packageVersion("Racmacs")
[1] ‘1.1.35’
> set.seed(850909)
> dat <- matrix(10*2^round(10*runif(100)), ncol=10)
> map <- make.acmap(dat, options = list(maxit=1))

Warning message:
In optimizeMap(map = map, number_of_dimensions = number_of_dimensions,  :
  There is some variation (12.23 AU for one point) in the top runs, this may be an indication that more optimization runs could help achieve a better optimum. If this still fails to help see ?unstableMaps for further possible causes.
