Reference to selected subset of an array\&. 

A \fBmask_array\fP is a reference to the actual elements of an array specified by a bitmask in the form of an array of bool\&. The way to get a \fBmask_array\fP is to call operator[](valarray<bool>) on a valarray\&. The returned \fBmask_array\fP then permits carrying operations out on the referenced subset of elements in the original valarray\&.
.PP
For example, if a \fBmask_array\fP is obtained using the array (false, true, false, true) as an argument, the mask array has two elements referring to array[1] and array[3] in the underlying array\&.
