coneInjection has been extended to include the functionality of
coneNozzleInjection, and the latter has been removed.
Some parameters have changed names. The "positionAxis" entry from
coneInjection has been removed in preferance of coneNozzleInjection's
single "position" and "direction" entries. This means that only one
injection site is possible per model (dictionary substitutions mean that
only minimal additions are required to add further injection sites with
the same parameters). The name of the velocity magnitude has been
standardised as "Umag" and "innerDiameter" and "outerDiamater" have been
renamed "dInner" and "dOuter" for consistency with the inner and outer
spray angles.
Velocity magnitude and diameters are no longer read when they are not
required.
The randomisation has been altered so that the injections generate a
uniform distribution on an cross section normal to the direction of
injection. Previously there was an unexplained bias towards the
centreline.
An example specification with a full list of parameters is shown below.

// - Or, inject with flow rate and discharge coefficient
// This also requires massTotal, dInner and dOuter

// - Or, inject at a pressure
/*

{
// The same as model1, but at a different position
$model1;
position (-0.15 0.1 0);
