New Features Added example of fitSpectraSMC with informative priors to the methanol vignette. Bug Fixes Removed the R package hyperSpec from Suggests because it is no longer available on CRAN. Fixed dependency on hyperSpec in Introduction vignette due to new CRAN check. This also affects the TAMRA dataset. Fixed a rare bug in reweighting that could potentially result in an infinite loop. Peak locations are now constrained to lie within the range of observed wavelengths. Locations are sorted to preserve identifiability. Fixed error in equations for FWHM in mixedVoigt & getVoigtParam as well as in both vignettes.
