Performance suggestion: Investigate "array-like" components

[carldlaird]

Investigate array-like components to allow for building of "indexed" components without the creation of a large number of small objects (e.g., components without the component datas).

@carldlaird How is this task different from #1159 ?

[carldlaird]

This is only part way towards what you are indicating in 1159 - it is not about vectorized operations - but actually about removing the existence of VarData and ParamData objects.

[carldlaird]

Where the goal is mostly to improve the construction time of large indexed vars and params - not much impact on expressions (and possibly a negative impact). Maybe I named this poorly - maybe it is a non-Data object implementation of Indexed components.
