Changes in XMBF 2.40:
---------------------

- Added the "Multifit" tool (command line option: -m ). This performs N successive fits, where the n-th fit uses just the n-th
data sample, rather than the average. This is an alternative to bootstrap, useful when the original data file has already been bootstrapped.

- If a bootstrap ensemble file is used (<use_bse_file>true</use_bse_file>), the number of bootstrap samples will now always be set according
to the header of the bse file, and the value specified via <bootstrap_samples>...</bootstrap_samples> will be ignored.

- the "MBF_to_XMBF" converter can now correctly read .mbf session files saved previously under a different operating system
(which may use different newline characters).
