Rules for setting LABELS in metaini files
A new Parameter [__LABELRULES] specifies how labels are attached to tests. The idea is to allow simple if/else structures in the following C-style form
[__LABELRULES]
<Condition> ? <LABEL1> : <LABEL2>
An example could be
[__LABELRULES]
{level} >= 5 && {permeability} == tensor ? NIGHTLY : CONTINUOUS
{gridtype} == ug ? CONTINUOUS : WEEKLY
