     MassSpecWavelet R package is aimed to process Mass Spectrometry
     (MS) data  mainly based on Wavelet Transforms. The current version
     only supports the  peak detection based on Continuous Wavelet
     Transform (CWT). Future versions  will include more functions
     covering entire MS data processes.
