save data, column Header, and column type definition to a *.lrn file

1	WriteLRN(FileName, Data, Header, Key, DataDefined, OutDirectory, CommentOrDigits)

`FileName`	string, name of the file to be written
`Data`	matrix of data , cases in rows , variables in columns, may contain NaN, NA or any other missing number symbol
`Header`	Optional: cell array or string matrix with column Header (d data columns) plus eventual header for Key as first entry
`Key`	Optional: a numeric vector, unique number for each line, by default 1:n, n being the number of data points
`DataDefined`	Optional: vector of column type: keys (0=ignore,1=data,2,3=class,9=key), default is only 1's with leading 9
`OutDirectory`	Optional: string, name of directory the data will be saved in, default `getwd()`
`CommentOrDigits`	either a string which is inserted as CommentOrDigits in the first line in the file. if it is a number then it is the number of significant digits (after the "."), default 6

Comfortably writes data to a file in the LRN Format. See dbt/ZFileFormatDocuments/lrn.html for a documentation of the format. The length of Key has to be ncol(Data) or ncol(Data[[1]]) respectively. If Key is empty it is replaced by a vector 1:ncol(Data) If Names is empty, it is replaced by default names: The default name for a DataDefined==9 column is 'Key'. The default name for a DataDefined==3 column is 'Cls'. The default name for DataDefined==1 or ==2 is 'C1', 'C2', etc. DataDefined may only contain numbers 0,1,2,3 and one 9. If DataDefined it is replaced by c(9,1,..).
