fix(FunctionNode): Improve error message when a non-function is called (#2494)
* fix(FunctionNode): Improve error message when a non-function is called

  Also adds tests for as many different varieties of function calls
  and their associate messages when the entity being called is not
  a function as I could come up with.

  Resolves #2493.

* feat(format): Add a truncate option to limit result length.

  Also uses the new option in FunctionNode.js to limit the length of the value
  portion of its new error messages. (As requested in review)

* docs: Add 'truncate' option to the list in the exported version of 'format'

feat(FunctionNode): allow function parameters to be called (#2443)
* feat(FunctionNode): allow function parameters to be called

  This change is implemented by checking if a function symbol is in
  the arg list, and if so delaying its analysis until evaluation time,
  at which point it is extracted from the arguments and called as
  appropriate depending on its rawArgs property.

  Also adds a few tests, documents the new facility, and documents the
  handling of free variables in a function definition, which was previously
  left undescribed.

  Resolves #2441.
  Resolves #2442.

* chore: correct lint violations (sorry)

fix: simplify.resolve detects reference loop and throws error (#2405)
* docs: Enhance generation to pick up functions with a prefix

  For example, prior to this commit, docgenerator.js would miss
  simplify.resolve because it is not a direct key of the math
  object.

  Also incorporates any "throws" attributes in the comments into
  the generated documentation, and uses this to document the
  new error-case behavior of simplify.resolve to be added in the next
  commit.

* fix(resolve): Detect and throw errors for reference loops

  Also extends resolve to work inside all node types. Adds tests
  for both changes.

* docs: Add embedded docs for simplify.resolve et al.

  To support finding the embedded doc from the `math.simplify.resolve`
  function itself, required extending the search for objects with
  documentation one level deeper in the `help()` function. Added test for
  this search.

  Also added support for documenting throws in embedded docs.

* refactor(simplify): Move resolve and simplifyCore to top-level

  Also reverts changes searching for docs and embedded docs one level
  down in the naming hierarchy.
  Also splits tests for resolve and simplifyCore into their own files,
  reflecting their new top-level status.

* fix(resolve): Remaining changes as requested

  Also removed a stray blank line inadvertently introduced in
  docgenerator.js

* refactor: Declare resolve and simplifyCore as dependencies of simplify

  ... rather than explicitly loading them, which is unnecessary now that they
  are at top level.

* fix: Add dependencies to factoriesNumber

  Also register simplifyCore as a dependency to rationalize

22a12567f8 feat: implement symbolicEqual function
Note for this to work in a broad variety of contexts, has to also allow
  identical expressions to cancel regardless of whether subtraction is
  always defined; but this seems safe in general, that x-x is 0 even if x
  does not generally have an additive inverse (for example, when working
  in the positive context).

  Resolves #1260.

feat: Add leafCount function (#2411)
This function returns the number of leaves in the parse tree of an
  expression. The motivation is to provide an initial complexity measure
  that could be used to decide whether or not to apply some simplification
  rules. Docs, embedded docs, and test cases are provided.

  Resolves #2389.

Word size suffix and BigNumber support for bin oct hex literals (#1996)
* added support for word size suffix in getToken

* Added check for zero in n2base.

* Removed old failing tests.

* Added some tests (failing).

* Extended 'format' function with 'base' and 'wordSize' options and changed 'bin', 'oct', and 'hex' to use 'format' function.

* Corrected a test.

* Fixed bignumber formatter.

* Added tests for math.format with 'base' and 'wordSize' options.
