Class
    Foam::Function1s::UniformTable
 
Description
    Tabulated property function that linearly interpolates between
    the UniformTable values.
 
Usage
    \table
        Property    | Description
        low         | Lower limit of the table
        high        | Upper limit of the table
        values      | Values, assumed uniformly distributed
    \endtable
