Composite map over the UK of CAPE , CIN

[fherreazcue]

Create a composite map over the UK of CAPE (background), CIN (semitransparent gray shading intervals, middle ground) and instantaneous precipitation rate (semitransparent precipitation color scheme, foreground).

Simulations: Control, Dom2

[fherreazcue]

Use SimRadarReflectivity1km to compute instantaneous precip (see #33 )
