Create/destroy a DVR with a runtime-defined data type

[raphschru]

Current state:

To create and destroy a DVR, its data type must be statically specified on the diagram:

In case we want to abstract the data type for the creation and destruction of the DVR, we have to use workarounds like using a DVR of a variant:

The problem is that it sacrifices data access efficiency for the sake of DVR creation/destruction genericity.

Idea:

Provide a way to create and destroy a DVR with a data type defined at runtime.

The "Create" node would take a variant for the its data type and output a U32 representing the reinterpreted strictly-typed reference.

The "Destroy" node would take the U32 and give back a variant containing the last value.

We could either have new nodes in the "Memory Control" palette, or just a new right-click option "✔Generic" on the existing nodes:

It would allow to manage the creation and destruction of DVRs generically (reducing boilerplate code), while still having DVRs of strict types (improving efficiency compared to a DVR of a variant).

Example usage:

1. A malleable VI for batch creation of DVRs specified in a cluster of DVRs:

2. Separation of data type definition and DVR instantiation:
