find_path_peak: Find the most interesting projection along a geodesic.
In tourr: Implement tour methods in pure R code

Find the most interesting projection along a geodesic.

1	find_path_peak(old, new, index, max_dist=pi/4)

`old`	currention project
`new`	projection that gives direction to travel in
`index`	interestingness index function
`max_dist`	maximum distance to travel along in radians

Use optimize to find the most interesting projection amongst all projections on a geodesic. This method assumes that the function is continuous with a single maximum, but seems to do ok even if there are multiple maxima.
