The gdal/swig/python/samples/ogr_layer_algebra.py should be promoted to an official Python script

Steps:

• move it to gdal/swig/python/scripts
• create a new test script for it in autotest/pyscripts/test_ogr_layer_algebra.py
• write a documentation page in doc/source/programs/ogr_layer_algebra (and link it to the index)

Currently vec.iter().rev() fails because DoubleEndedIterator is not implemented for MatrixIter. By a quick layman's glance at the source it seems straightforward to imp

Add Runnable links of the code below the example.
Use link name Run Code which links to a Online C++ complier conatining the example code.
Use Rextester as the Online C++ Compiler (If you have a better suggesstion please comment).

Follow below steps to generate the Run Code Link.

1. Go to Rextester
2. Copy or write the example

An option like $ fio cat --bounds w s e n --bounds-crs <crs> --dst-crs <crs> would allow for filtering prior to reprojection, like $ ogr2ogr -spat w s e n -spat_srs <crs>.

See Toblerity/Fiona#210 for a discussion about standardizing bounding boxes as --bounds w s e n rather than --bbox w,s,e,n.
