c3a978b9da [FEATURE][processing] Snap geometries to layer algorithm 
Port the Geometry Snapper plugin across to the analysis lib, and
expose to python bindings

Add a new algorithm which performs the snapping to layers

f65e770242 [FEATURE[processing] New algorithm to compute geometry by expression 
This algorithm updates existing geometries (or creates new
geometries) for input features by use of a QGIS expression. This
allows complex geometry modifications which can utilise all the
flexibility of the QGIS expression engine to manipulate and create
geometries for output features.

82312e10e4 [FEATURE][processing] New algorithm to extract specific nodes 
This algorithm allows you to extract specific nodes from geometries.
Eg you can extract the first or last node in the geometry.

The algorithm accepts a comma separated list of node indices to
extract, eg 0 = first node, 1 = second node, etc. Negative indices
can be used to extract nodes from the end of the geometry. Eg
-1 = last node, -2 = second last node.

86368f39c3 [processing] Optimise feature requests within qgis algs 
- don't use setFilterFid() within loops to fetch features one

outside the loop
- don't fetch unused attributes/geometry when it can be
avoided
