WITec Project exports the spectra names (contain information of map position or number of spectra) within the file.
WITec Project exports the spectra units within the file.

read.txt.Witec reads Witec ASCII files where the first column gives the wavelength
axes and the other columns the spectra. read.dat.Witec reads Witec's ASCII exported data
which comes in separate files with x and y data.
