Short:
------
AAVERAGE() Determines average of an array with condition
Returns:
--------
<nAverage> => Average of the array
Syntax:
-------
AAVERAGE(aTarget,[bCondition])
Description:
------------
<aTarget> is the target array. Normally an array of numeric values.
[bCondition] is an optional codeblock used to select
a subset of the array. This could be used to filter out 0's or
non-numeric elements. The block must accept an array element as
a parameter, and return true or false <expL> to determine if
this element is part of the desired subset.

v := AAVERAGE(aSales)
v := AAVERAGE(aSales,{|e|valtype(e)=="N".and.e<>0})
