Index function for a TensKind

Wraps the call to the Indexer class method The index is built in this way. Let us assume three component case

a+Na*(b+Nb*c)

this is changed into a more homogeneous

a+Na*(b+Nb*(c+Nc*0))

so that every component needs to perform the following operation

i+N*ext

where ext is the result of the calculation for the outer component. Starting from 0, the calculation ends when no more component is present (terminating case).

Parameters

dynSizes	Sizes of the dynamical components
args	Components index
