file.itp_c, which implements the ITP algorithm
entirely in C++.f to the function itp() can
now be either an R function or an external pointer to a C++ function. In
the latter case, itp() makes use of the Passing
user-supplied C++ functions framework offered by the Rcpp package.
For the simple examples given in the itp package only a
modest improvement in speed is observed (and expected). However, being
able to call itp() on the C++ side may have benefits in
more challenging problems.f

interval has been fixed. It caused incorrect results in cases where the
function is locally decreasing.
