The method smtk::mesh::PointSet::find is extremely slow, and should be
used only as a last resort. This commit replaces a call to find()
within a tight loop with the construction and repeated query of a hash
map.

NOTE: with this update, the mesh session now loads large datasets as
quickly as the VTK session.

3d9b9c9f CreateUniformGrid: set mesh collection as model tessellation
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !1329

This update enforces the following behaviors:

  1. When resoures are loaded via File->Open, ParaView semantics
  apply: the apply button must be pressed to complete opening the
  file. This matches the functionality of the other ParaView readers
  (that are selectable when there are multiple readers for a file
  type).

  2. When a resource is created via File->New Resource, a modal dialog
  is presented to the user. When the user presses apply on the dialog,
  the resource is generated and its representation is rendered. The
  Properties Panel's apply button is never enabled. NOTE: the original
  plan was to move the contents of the modal dialog to the Properties
  Panel. This worked, but it looked pretty bad and was not intuitive.

  3. When a resource is created by an operation from the Operation
  Panel, the resource is generated and its representation is
  rendered. The Properties Panel's apply button is never enabled.

The function evaluation feature in SimpleExpression view relies on VTK.
However, also do we want to be able to preview this view with only Qt
enabled. In order to do so this MR creates a subclass of qtSimpleExpressionView
and it would override the SimpleExpression view constructor at runtime.
That being said now users can preview it with only Qt enabled and do
function evaluation when both Qt and VTK are enabled.

The current pattern in SMTK is to have resources and components. To
retrofit smtk::mesh to fit this pattern, we introduce
smtk::mesh::Component, a lightweight, shared object that provides
access to a meshset.
