Update to FriCAS 1.1.6

Notable changes in FriCAS 1.1.6 (compared to version 1.1.5):

- Added experimental graph theory package.

- Added power series expanders for Weierstrass elliptic
  functions at 0.

- New functions: kroneckerProduct and kroneckerSum for matrices,
  numeric weierstrassInvariants and modularInvariantJ, symbolic
  Jacobi Zeta, double float numeric elliptic integrals.

- New domains for vectors and matrices of unsigned 8 and 16 bit integers.

- Changes to Spad compiler: underscores which are not needed as escape
  are now significant in Spad names and strings, macros with parameters
  are supported, added partial support for exceptions, braces can
  be used for grouping.

- A few speedups.

- Reduced disc space usage during build.

Bug fixes, in particular:

  implementations.

Notable changes in FriCAS 1.1.5 (compared to version 1.1.4):

- Added numeric version of lambertW.

  only).

- New categoris CoercibleFrom and ConvertibleFrom.  New domain
  for ordinals up to epsilon0.  New domain for matrices of machine
  integers.  New package for solving linear equations written as
  expressions (faster then general expression solver).

- Functions exported by Product() are now called 'construct', 'first'
  and 'second' (instead of 'makeprod', 'selectfirst' and 'selectsecond'
  respectively).

- Some functions are now much faster, in particular bivariate
  factorization over small finite fields.

- When using sbcl FriCAS now tries to preload statistical profiler.

Bug fixes, in particular:

Notable changes in FriCAS 1.1.4 (compared to version 1.1.3):

- New domains for combinatorial probability theory by Franz Lehner.

- Improved integration of algebraic functions.

- Updated framework for theory of computations.

- In Spad parser '**', '^' and '->' are now
  right-associative.

- Spad parser now longer transforms relational operators.

- Retraction of 'rootOf' from Expression(Integer) to AlgebraicNumber
  works now.

- Attempt to print error message about invalid type no longer
  crash (SF 2977357).

- Fixed few problems in Spad compiler dealing with conditional exports.

- HyperDoc now should find all function descriptions (previously
  it missed several).

Update to FriCAS 1.1.3

Changes:

- Added "jet bundle" framework  by Werner Seiler and Joachim Schue,
  which includes completion procedure and symmetry analysis for PDE.

- Better splitting of group representations (added Holt-Rees improvement
  to meatAxe).

- Added numeric versions of some elliptic integrals and few more elliptic
  functions.

- Speeded up FFCGP (finite fields via Zech logarithms).

- New experimental flag (off by default, set via setSimplifyDenomsFlag)
  which if on causes removal of irrationalities from denominators.
  Usually it causes slowdown, but on some examples gives huge speedup.
  It may go away in future (when no longer needed).

- Added experimental framework for theory of computations.

Bug fixes, in particular:

- Numerical solutions of polynomial systems have now required accuracy
  (SF 2418832).

- Fixed problem with crashes during tracing.

- Fixed a problem with nested iteration (SF 3016806).

- Eliminated stack overflow when concatenating long lists.

Log message:
Update FriCAS to 1.1.2

Changes:

- Experimental Texmacs interface and Texmacs format output.
- Guessing package can now guess algebraic dependencies.
- Expansion into Taylor series and limits now work for most
  special functions.
- Spad to Aldor translator is removed.
- Spad compiler no longer allows to denote sets using braces.

Bug fixes, in particular:

- Fixed few cases where elementary integrals were returned
  unevaluated or produced wrong results.
- Unwanted numerical evaluation should be no longer a problem
  (FriCAS interpreter now very strongly prefers symbolic
  evaluation over numerical evaluation).
- Fixed a truncation bug in guessing package which causes loss
  of some correct solutions.
- TeX and MathML format should correctly put parentheses around
  and inside sums and products.
- Fixes few problems with handling of Unicode.

Update to FriCAS 1.1.1

Notable changes since version 1.1.0:

- New graphics framework.
- Support for using GMP with sbcl on 32/64 bit AMD/Intel processors
  (to activate it one must use '--with-gmp' option to configure).
- Improvements to integration and normalization.  In particular
  integrals containing multiple non-nested roots should now work
  much faster.  Also FriCAS now can compute more integrals
  of Liouvillian functions.
- Several new special functions.
- Improvements to efricas.
- Looking for default init file FriCAS now first tries to use
  '.fricas.input' and only if that fails it looks for
  '.axiom.input'.

Bug fixes, in particular:

- Numeric atan, asin and acos took wrong branch.
- WeierstrassPreparation package did not work.
- Saving and restoring history should be now more reliable.
- Fixed two bugs in Spad compiler related to conditional compilation.
- Fixed a problem with rational reconstruction which affected
  guessing package.
