Add auxiliary scripts for handling matrices and linear programming tableaus efficiently
Add updates to compoundProblem5 behavior
Add LinearInequality command to specify equations of the from 5x1+2x2<=4
This is based mostly on parserImplicitPlane.pl
It is used in writing linear programming problems
Add comment :
Add default value for {implicit}

This shouldn't be needed -- not sure how this key can be left undefined.
Add hack to check ImplictPlanes and LinearInequalities in lists
Fix unintended bug created by LinearInequality hack.

sometimes the top level self is an array rather than a HASH.
Modifications from Davide to allow LinearInequality to be used in lists.
Switch to using geogebra4.4 from geogebra4.2
Add conversion from MathObjects matrix to array references for
macros defined in LinearProgramming.pl
Add creation of syntactic sugar subroutine via INITIALIZE_SCAFFOLD
Fix quote marks in VERSION
Remove some error comments
Fix error that made solutions print badly in TeX mode
Main fix is to apply EV3 to input BEFORE feeding it to solution
The rest is just to bring this code in line with the SOLUTION code in PGbasicmacros.pl
Make displaying top labels work with MathJax
and with printing matrices
Correct comment
Removing eval {} commands which are caught on hosted2 (but not on my laptop) ??
Fix typo in PG/Translator.pm replacing END_PGML_SOLUTION  with END_PGML_HINT

This fixes bug #2682
Added to documentation.

If a problem value is negative, then don't display points (used in library browser).
(cherry picked from commit 723d872e65fecb37865d248365d142b389b89543)
