/** \def BOOST_VMD_EQUAL(sequence,...)

\brief Tests any two sequences for equality.

sequence     = First sequence. <br/>
...          = variadic parameters, maximum of 2.

The first variadic parameter is required and is the second sequence to test.
The optional second variadic parameter is a VMD type as a filter.

The macro tests any two sequences for equality. For sequences to be equal the
VMD types of each sequence must be equal and the individual elements of the
sequence must be equal. For Boost PP composite types the macro tests that
the composite types have the same size and then tests that each element
of the composite type is equal. This means that all elements of a composite
type must be a VMD type in order to use this macro successfully.

The single optional parameter is a filter. The filter is a VMD type which specifies
that both sequences to test must be of that VMD type, as well as being equal to
each other, for the test to succeed.

returns   = 1 upon success or 0 upon failure. Success means that both sequences are
equal and, if the optional parameter is specified, that the sequences are
of the optional VMD type.
