A good 2 days after 0.7.6 was released, here comes Rcpp 0.7.7. The reason for this release is that a subtle bug installed itself and we did not catch it in time

The new version also includes two new class templates : unary_call and binary_call that help integration of calls (e.g. Rcpp::Language objects) with STL algorithms. For example here is how we might use unary_call

This emulates the code

> lapply( 1:10, function(n) seq(from=n, to = 0 ) )

As usual, more examples in the unit tests
