* \@ifnextchar consumes spaces
Fix#2117 by fixing our implementation of \@ifnextchar to match LaTeX's:
consuming spaces before checking the next character. See #2117 for details.
* Update MacroContextInterface
* Remove forced \normalsize in \raisebox
Fix#1786 (incorrect size of "E" in `\TeX`) by fixing `\raisebox` to
keep the current font size. Previously, `\raisebox` was rendering its
second argument as if it were in `\normalsize\textrm{...}`; now,
the argument is just as if it were in `\textrm{...}`.

* Rewrite spacing commands as macros
Fix#1130 by defining `\!`, `\negthinspace`, `\,`, `\thinspace`, `\:`,
`\medspace`, `\;`, `\thickspace`, `\negmedspace`, `\negthickspace`,
`\enspace`, `\enskip`, `\qquad`, `\quad` as macros.
Fix#1036 by defining a new `SpaceNode` in mathMLTree that recognizes
all special space amounts from
https://www.w3.org/TR/2000/WD-MathML2-20000328/chapter6.html

* 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
