Extending te_variable functions

[loumalouomega]

Adding:

    {"zIsEqual", IsEqual,               TE_FUNCTION2 | TE_FLAG_PURE, 0},
    {"zIsGreater", IsGreater,           TE_FUNCTION2 | TE_FLAG_PURE, 0},
    {"zIsGreaterEqual", IsGreaterEqual, TE_FUNCTION2 | TE_FLAG_PURE, 0},
    {"zIsLess", IsLess,                 TE_FUNCTION2 | TE_FLAG_PURE, 0},
    {"zIsLessEqual", IsLessEqual,       TE_FUNCTION2 | TE_FLAG_PURE, 0},

This bring the changes we have added to our project https://github.com/KratosMultiphysics/Kratos/

Hello

Greetings

Thanks for the patch. Comparison as zIsGreater(a,b) functions overlaps with the logic branch, which does this as real operators, and the z-prefix naming is driven by the alphabetical lookup rather than by what's good to type. Closing, see CONTRIBUTING. TinyExpr is small enough that you can add this yourself in a fork. It only stays that way if I don't implement every request like this one.

OKay, I just wanted to contribute with the changes we applied in our system.
