\brief Determines if a sequence is a Boost PP array.
|

|
|

|
|
The macro checks that the sequence is a Boost PP array.
|

It returns 1 if it is an array, else if returns 0.

returns = 1 if it is an array, else returns 0.

The macro will generate a preprocessing error if the input
|

|
|
is in the form of an array but its first tuple element, instead
|
||
|
|
of being a number, is a preprocessor token which VMD cannot parse,
|

as in the example '(&2,(0,1))' which is a valid tuple but an invalid

array.
