NEWS: minor correction (adding cjzilverberg as contributor to identify the problem with 1D functions)

minor bug fixed. Thanks to Aaron Jones. This bug might have triggered when the user provided more than 1 parameter set as a first guess for the optimal solution

observations (in 'obs' or 'Observations.txt') are allowed to be of class ('Date', 'POSIXct', 'POSIXt'), not only 'Date' as before this enhancement

CITATION file modified to allow working without package installed (following CRAN request). DOI field added to CITATION.

New field 'Additional_repositories' in the DESCRIPTION file, and minor modifications to the 'Description' field

'lhoat' now works ok on Windows machine ('parallel='parallelWin') R CMD check --as-cran hydroPSO_0.3-3-5.tar.gz 

'lhoat'now works correctly when 'parallel' is in c('multicore', 'parallelWin') AND 'write2disk=FALSE'

updated NEWS file. The 'Dimension' field is now correctly written into the 'PSO_logfile.txt' when 'parallel!=none'

'lhoat': -) when 'normalise=TRUE' the 'ParameterSets' output is now given in the real range of each parameter

hydroPSO: when 'fn.name!=hydromod' AND 'normalise=TRUE' the function 'fn' is now evaluated with the correct (non normalised) parameter values

'hydroPSO': minor bug fixed. When the goodness-of-fit value of a given parameter set is not finite, the parameter values are now correctly written

pest2hydroPSO':now it handles correctly cases where the fifth row of 'pst.fname' uses tab instead of white spaces as separator
