* Normalizations
    * Nick & Jimmy met last week about normalizations
    * GEM challenge: models in different regimes with different approximations.  
    * What should your overall normalization class be when comparing MHD (which has no scales) with PIC?
    * New `PhysicalType` class in `astropy.units` (v4.3)
    * Maybe we can get a normalization from a `PhysicalType`.  Perhaps we get normalizations for fundamental SI units, and then have a function that gets the normalization for a specific physical type
    * MHD has no inherent scale, but other systems that we use do
    * Molecular dynamics : Length is usually in units of the Wigner-Seitz radius, and time in units of plasma frequency. 
    * Ideally the `Normalization` class would
