Henry Weller 0dd2e97bd8 CodedFunction1: New Function1 which uses codeStream to dynamically compile the value function code
For example in the new tutorial case:
tutorials/incompressible/pimpleFoam/laminar/pitzDailyPulse
a cosine bell velocity pulse is specified at the inlet by directly defining the
code for it:

    inlet
    {
        type            uniformFixedValue;
        uniformValue    coded;

        name            pulse;

        codeInclude
        #{
            #include "mathematicalConstants.H"
        #};

        code
        #{
            return vector
            (
                0.5*(1 - cos(constant::mathematical::twoPi*min(x/0.3, 1))),
                0,
                0
            );
        #};
    }

which is then compiled automatically and linked into the running pimpleFoam
dynamically and executed to set the inlet velocity.
