Implemented unit tests for JclExprEval to test it (tests can be copied to Excel to test the tests).

What do you mean by "did not adhere to correct evaluation order"?
Can you give some examples of what was wrong?

[bennybechdk]

Sorry for not giving examples (obviously needed for review).

Example:
3*100^2*2 should give a result of 60000 (like it does in Excel)
In the old version it was parsed as (3*100)^2*2 giving 180000
The new version parses it as 3*(100^2)*2 giving 60000

3100^22 should give a result of 60000 (like it does in Excel)

Please put the equations in a [code] block (ex. 3*100^2*2), so the * doesn't get removed - now the samples don't make sense.
