Delimited expressions within function calls to prevent denominators from continuing beyond commas.
Allow latex to adjust size of parentheses according to expression within.
Replaced ^ with \uparrow (less misleading - latex maths doesn't understand operator precedence or words).
Replaced abs(x) with |x| when x does not contain brackets. check-in: 3e6154ff3d user: geraint@users.sourceforge.net tags: origin/master, trunk

These changes produce the desired result (optimised algebraic equations) but
have highlighted a problem; when optimisation fails, Reduce does not write
a result. For complicated systems, this can lead to missing assignments in
the resultant code. check-in: ea9834becc user: geraint@users.sourceforge.net tags: origin/optimise-algebraic-equations, trunk

Equation solving requires the Matlab Optimization Toolbox to be installed.

Code has been changed from C++ to C to allow mex files to be built with LCC,
the compiler bundled with Matlab.

Parameters are now obtained from numpar.c instead of a dialogue box.

`mtt <sys> sfun zip` creates all necessary files for building the model mex files. check-in: 062029b187 user: geraint@users.sourceforge.net tags: origin/master, trunk
