    Renamed the page Spec to Spectrum.

    What’s the precise idea of where the two senses of spectrum meet, that the spectrum of the sphere spectrum has Morava-K theories as points (arXiv:1401.1044, p. 10)?

    I have added the statement that in SpectraSpectra homotopy cartesian squares are equivalently homotopy cocartesian, with some remarks and pointers.

    Also re-organized slightly and added cross-link with stable homotopy category.

    Ah, now I see why this page was so empty: There is also stable (infinity,1)-category of spectra and the two should probably be merged.

    Hm, it may be tedious to merge these entries in a satisfactory way. Maybe instead I’ll give the section on finite homotopy (co)limits of spectra its own stand-alone entry, for ease of !include-ing it into relevant entries (such as these two, but also stable homotopy category etc.).
