Class for DSP + meta-data

[ipashchenko]

What about to join dsp array and it's metadata in one class? That class should have methods to de-disperse dsp array, average it, etc. Check frames.Frame class that handles dynamical spectra operations. If your code can create instance of that class from m5 files then we can pass this instance right to software for preprocessing (optionally, e.g. de-dispersion) and searching candidates (i've just created Searcher class that implements something like that:)

Good idea. Must do it...
