Class
    Foam::Function1s::Uniform

Description
    Templated function that returns a constant value.

    Provides backward-compatibility for cases where a field is spatially
    "uniform" and may be treated as a constant value.

    Usage - for entry \<entryName\> returning the value <value>:
    \verbatim
        <entryName>    uniform  <value>
    \endverbatim
