Class
    Foam::timeActivatedExplicitMulticomponentPointSourceNew

Description
    Provides a mechanism to introduce point sources to a set of carrier fields.
    Carrier fields are supplied on consruction, and interrogated to provide the
    field indices of the sources.

    Source values are assumed to be in <quantity>/s, and divided through by the
    cell volumes before being returned, e.g. for a kg/s source

    Properties are described in a <name>Properties dictionary

    active          true;       // are sources active (true/false)

    pointSources
    (
        source1                 // source name
