This ports to old (pre 2.0!!) topocolor plugin to processing. It's based
off my beta 2.x fork (never publicly released) which implemented
a bunch of improvements to the algorithm allowing for minimal number
of required colors and also balanced counts of features assigned
each individual color.
** Pretty sure this plugin was highlighted in Victor's presentation
about plugins-which-shouldn't-be-plugins-and-should-be-processing-algs
instead. It's a prime example of a plugin where the amount of code
required for gui+setup exceeded the actual "guts" of the plugin by
a huge factor, and which is much more useful when it can be
integrated into a larger processing model.
If you have a layer with an unknown CRS, this algorithm gives a list
of possible candidate CRSes which the layer could be in.
It allows users to set the area (and corresponding CRS) which they know
the layer should be located near. The algorithm then tests every CRS
in the database to see what candidate CRSes would cause the layer
to be located at that preset area.
It's much faster than it sounds!! (just a couple of seconds)

Adds a new QgsGeometry::orthagonalize method which tries to make
angles in geometries either right angles or straight lines
Also adds a processing algorithm exposing this feature.
Replaces the existing 'Basic Stats for Numeric Fields' and
'Basic Stats for String Fields' algorithms and adds support
for date/time/datetime fields.
Having a single unified algorithm allows more flexible models
where a field type may not be known in advance.
Deprecate existing basic stats algorithms
Copy min area parameter from 'Fill holes' algorithm to 'delete
holes' algorithm.
Also:
- make algorithm maintain z/m values
- make algorithm work with curved geometries
- add unit tests
