Clearer SVD

The line in:

decomp = np.linalg.svd(y_scale.T)

can be written more clearly as:

U, s, V = np.linalg.svd(y_scale.T)

Subsequent lines that use decomp can then be replaced with:

    if npc == None:
        cs = np.cumsum(s ** 2) / np.sum(s ** 2) * 100.
        npc = np.where(cs > percVar)[0][0] + 1

    if ncores > npc:
        ncores = npc

    basis = np.dot(U[:, :npc], np.diag(s[:npc]))
    newy = V[:npc, :]

Note: I haven't checked of U, s, and V we're used elsewhere.
