Mark Baker 291ea88a6c Initial work enabling Excel function implementations for handling arrays as arguments when used in "array formulae". (#2562)
* Initial work enabling Excel function implementations for handling arrays as aguments when used in "array formulae".

So far:
 - handling for single argument functions
 - for functions where only one of the arguments is an array (a matrix or a row/column vector)
 - for when there are two array arguments, and one is a row vector, the other a column vector
 - for when there are either 2 row vectors, or 2 column vectors
 - for a matrix and either a row or column vector 

Will work ok, as long as there are no more than two array arguments; still need to identify the logic to apply when there are more than two arrays; or there are two that aren't an already supported row vector/column vector pairing (ie two matrices).

* Throw an exception if we have three or more array arguments (after flattening) passed to a supported function until we can identify the abstruse non-euclidian logic behind how Excel handles building, using and presenting those n-dimensional result arrays

* Implement array arguments for the DATE() function so that we can verify that paired arrays/vectors work with functions that support more than 2 arguments

* Implement array arguments for the many of the Math/Trig functions

* Update change log
