VERSION 0.1-3

o as.lm and as.lm.nls can be used to convert an "nls" object to an 
  "lm" object which is tangent to the nls object.  Untested.

o as.lm.nls uses proto package hence new dependency

o added algorithm = "random" which samples maxiter rows from start if
  start is a data frame with more than 2 rows whereas if start is a data
  frame with exactly 2 rows it will take maxiter random points from the
  rectangle whose boundary is defined by the rows.

o if nls exits with an error nls2 uses NA as the return value of that nls
  call instead of stopping with an error

VERSION 0.1-2

o fixed problem with update not working with objects produced by nls2.

o fixed number of iterations and tolerance displayed when using
  algorithm = "brute-force".

o if there are exactly two rows in start= then a grid of starting values
  is formed so that there are at least maxiter points on the grid.

o start can be an nls object in which case coef(nls) is used.

VERSION 0.1-1

o documentation and DESCRIPTION file tweaks.

VERSION 0.1-0

o initial release.
