The `From` and `To` nomenclature for topology mapping has been confusing for
both users and developers, especially at lower levels where the intention of
mapping attributes from one element to another is easily conflated with the
concept of mapping indices (which maps in the exact opposite direction).
These identifiers have been renamed to `VisitTopology` and `IncidentTopology`
to clarify the direction of the mapping. The order in which these template
parameters are specified for `WorkletMapTopology` have also been reversed,
since eventually there may be more than one `IncidentTopology`, and having
`IncidentTopology` at the end will allow us to replace it with a variadic
template parameter pack in the future.
Other implementation details supporting these worklets, include `Fetch` tags,
`Connectivity` classes, and methods on the various `CellSet` classes (such as
`PrepareForInput` have also reversed their template arguments. These will need
to be cautiously updated.
The convenience implementations of `WorkletMapTopology` have been renamed for
clarity as follows:
```
WorkletMapPointToCell --> WorkletVisitCellsWithPoints
WorkletMapCellToPoint --> WorkletVisitPointsWithCells
```
The `ControlSignature` tags have been renamed as follows:
```
FieldInTo --> FieldInVisit
FieldInFrom --> FieldInMap
FromCount --> IncidentElementCount
FromIndices --> IncidentElementIndices
```
This is done to avoid warnings when compiling VTK-m consumers
with different defaults for symbol visiblity. AKA avoid warnings
like:
```
warning: ‘vtkm::worklet::WorkletMapField’ declared with greater visibility than the type of its field ‘vtkm::worklet::WorkletMapField::<anonymous>’ [-Wattributes]
class WorkletMapField : public vtkm::worklet::internal::WorkletBase
^~~~~~~~~~~~~~~
```
The Invoker is a control side object that handles the construction
of the relevant worklet dispatcher. Moving it to control makes it
obvious that it isn't an algorithm itself but a way to launch
worklets.

There was a special case for ArrayHandleMultiplexer where if you gave it
just one type it would treat that as a value type rather than an array
to support and instead provide a default list of types. However, GCC 4.8
is having trouble compiling the code to create the default list, the
semantics are confusing, and the more I think about it the less likely I
think we will need this functionality. So, just getting rid of that.
Although it is mostly C++11 compliant, GCC 4.8 does not have an
implementation of std::aligned_union. We cannot drop this compiler, so
provide our own implementation in that case.

Previously, templates were used in the implementation of CastAndCall to
find the type and call the underlying function. The templates checked
one type at a time.
However, compilers were not always great at optimizing a 15-call deep
stack with an if statement at each one. Instead, use a case statement in
a single function block. This requires providing separate code for each
number of types. Currently, up to 20 are created (with pyexpander). If
there are more than that, then the template recurses.
Previously the "dynamic" array was taken from a VariantArrayHandle.
However, the VariantArrayHandle will actually cast to a basic array, so
the comparison is not particularly fair. Change that to an
ArrayHandleVirtual so that it is actually calling through a virtual
method.
Also make 2 versions of the multiplexer test. The first version has an
array that is at the 1st index and the second is at the last index. This
tests whether the compiled code has to do lots of actual comparisons to
get to the last index.
The code was working fine on all the dashboards except for the Visual
Studio 2015 compiles on delve. It gave an error like:
ArrayHandleMultiplexer.h(398): error C2938: 'ArrayHandleToStorageTag<unknown-type>' : Failed to specialize alias template
A StackOverflow article (https://stackoverflow.com/questions/43411542/
metaprogramming-failed-to-specialize-alias-template) suggests that this
is a bug in older versions of Visual Studio. Although fixed in more
recent versions, we might have to support older versions.
Currently, ListTags are implemented by having a subtype name list set to
a brigand::list. However, there is always a chance this will change. To
make things more explicit, create a vtkm::internal::ListTagToBrigandList
to make it clear what the resulting type should be (and provide some
potential future-proofing).
Also add a convenient vtkm::ListTagApply that allows you to easily
instantiate a template with the list of types in a ListTag.
vtkm::internal::Variant is a simplified version of C++17's std::variant
or boost's variant. It is a template that takes a list of types. The
Variant may be set to any one of those types. A CastAndCall allows you
to call a functor with the appropriately cast type.

Acked-by: Kitware Robot <kwrobot@kitware.com>

Previously, IsWriteableArrayHandle just checked to see if an
ArrayHandle's portal has a ValueType of void* because we had coded the
special read-only array handles to have fake portals for writing.
However, we recently removed that because it was more trouble than it
was worth. Now IsWritableArrayHandle checks for the existance of the Set
method. If it does not exist, then the portal is considered read-only.
Also corrected spelling (writeable -> writable).
