D.1c Continuous Wavelet Transform time-series analysis and filtering tool

1d & 2d continuous wavelet transform (CWT) to find time-dependent oscillatory signals, and to detect features of given scale in images. The 1d CWT comes with the Morlet wavlet to detect quasi-oscillatory signals. Statistically relevant scale-time tracks are extracted automatically. A visualization function is provided. The 2d CWT has several mother wavelets available. The Mexican-Hat wavelet allows for the detection of edges and blobs at given scales, filtering and the building of scale-space representations. Documentation, in the form of a PDF, for the wavelet tool is ready. The wavelet module has been uploaded to the website and is ready for testing.
