Editing WoW:API GetSpellCritChance

{{wowapi}}
Returns a players critical hit chance with spells for a certain school.

<pre>theCritChance = GetSpellCritChance(school)</pre>

=== Parameters ===
''school'' - the spell school to retrieve the crit chance for
* 1 for Physical
* 2 for Holy
* 3 for Fire
* 4 for Nature
* 5 for Frost
* 6 for Shadow
* 7 for Arcane

=== Returns ===
An unformatted floating point figure representing the critical hit chance for the specified school.

=== Example ===

The following function, called with no arguments, will return the same spell crit value as shown on the Character pane of the default UI.  The figure returned is formatted as a floating-point figure out to two decimal places.

<pre>function GetRealSpellCrit()

    local holySchool = 2;
    local minCrit = GetSpellCritChance(holySchool);
    local spellCrit;

    this.spellCrit = {};
    this.spellCrit[holySchool] = minCrit;

    for i=(holySchool+1), 7 do

        spellCrit = GetSpellCritChance(i);
        minCrit = min(minCrit, spellCrit);
        this.spellCrit[i] = spellCrit;

    end

    minCrit = format("%.2f%%", minCrit);
    return minCrit;

end</pre>

The above function is essentially a straight copy of the function from the Paper Doll LUA file in the default UI.
