def CellMLToNektar.pycml.reduce_commutative_nary._reduce (   self )

Reduce this expression by evaluating its static parts.

If the whole expression is static, proceed as normal for an
<apply>.  Otherwise check if we have more than one static
operand.  If we do, we can combine them in a new static
expression and evaluate that as a whole.
