0ac4b6e89d Convert ParseNode to struct (#1534)
* Define the nested version of ParseNodes structs explicitly.

Passes test:jest, but fails test:flow.

* Fix additional type errors reported by flow.

* Migrate rebased code from master.

* Rename ParseNode.js to parseNode.js.

* Update defineEnvironment output type to fix the flow errors in environment/array.js.

19d2aa63c3 Replace ParseNode<*> with a more accurate AnyParseNode and fix flow errors. (#1387)
* Replace ParseNode<*> with a more accurate AnyParseNode and fix flow errors.

* Allow "array" environment type spec to use any all symbol type.

Before this commit, it was constrained to use "mathord" and "textord", but a
recent change in HEAD resulted in a "rel" node being used in the spec for, e.g.
\begin{array}{|l||c:r::}\end{array}

* Address reviewer comments: rename `lastRow` to `row` in array.js.

acccce801d \def support (and \gdef and \global\def) (#1348)
* Nested environments of macro definitions

* Rename environment -> namespace

* \def support

* Clean up \df@tag at beginning

* \global\def support

* Fix \global via new setMacro helper

* Fix caching behavior and build array on top of it

Also avoid double lookup of macros

* Add tests

* Add argument tests

* Remove global pointer

* Note about macros object being modified

* add __defineMacro

* Add \global\def test

* More \global tests

* Constant-time lookup

Rewrite to use an "undo" stack similar to TeX, so get and set are
constant-time operations.  get() still has to check two objects: one with all
current settings, and then the built-ins.  Local set() sets the current value
and (when appropriate) adds an undo operation to the undo stack.  Global set()
still takes time linear in the number of groups, possibly changing the undo
operation at every level.

`Namespace` now refers to a space of things like macros or lengths.

* Add \def to-dos

* Put optional arguments in their own group

* Rename `pushNamespace` -> `beginGroup`

* Wrap each expression in a group namespace

* Add comments

a0ddad338e Support \tag, \tag*, and \gdef (#1309)
* Tag sketch

* Drop objectAssign; already using Object.assign elsewhere

* Basic \gdef support

* Bug fix

* Finish \tag

* MathML numbers equations with <mlabeledtr>

* Fix flow bugs

* \gdef tests

  * No more \@tag function; it was essentially just doing \text
* Wrap tag in group so e.g. ( and ) are formatted the same
* Add `feed` method to MacroExpander for multiple inputs (for tag)
* Bug fixes in buildHTML, makeTextRow, _getBuilt (for display mode)

5a4aedd882 Make ParseNode value payload and defineFunction handler functions type-safe (#1276)
* Make ParseNode `value` payload type-safe.

* Make defineFunction handlers aware of ParseNode data types.

* Add `type` to all function definitions to help determine handler return type.

* Added unit test for case caught only in screenshot test and fixed issue.

* Rename some symbol `Group`s to avoid conflicts with `ParseNode` groups.

Symbol `Group`s are also used as `ParseNode` types. However, `ParseNode`s of
these types always contain a raw text token as opposed to any structured
content. These `ParseNode`s are passed as arguments into function handlers to
create more semantical `ParseNode`s with more structure.

Before this change, "accent" and "op" were both symbol `Group`s and `ParseNode`
types. With this change, these two types (the raw accent token `ParseNode`, and
the structured semantical `ParseNode` are separated for better type-safety on
the `ParseNode` payload).

* stretchy: Remove FlowFixMe for a forced typecast that's no longer needed.

fd18f6979e Add an optional settings argument to render calls
Summary:
Add the ability to pass in options to the render calls which contain information about the parse. This information is passed around to the parser and builder, which parse and render differently depending on the options. Currently, this includes an option to render the math in display mode (i.e. centered, block level, and in displaystyle).

Also added some changes to make it easier to add new data to functions (now that new data doesn't need to be copied into the ParseFuncOrArg data structure, it is looked up when it is needed) and has more sane support for the `'original'` argType (as suggested by pull request #93).

Test Plan:
 - Make sure tests and lint pass
 - Make sure huxley screenshots didn't change, and new screenshot looks correct
