A StripTopology in which the component strips subtend a constant angular width, and, if projected, intersect at a point.
WARNING! Wherever 'float strip' is used the units of 'strip' are angular widths of each strip. The range is from 0.0 at the extreme edge of the 'first' strip at one edge of the detector, to nstrip*angular width at the other edge.
The centre of the first strip is at strip = 0.5
The centre of the last strip is at strip = 0.5 + (nstrip-1)
This is for consistency with CommonDet usage of 'float strip' (but where units are strip pitch rather than strip angular width.)
WARNING! If the mid-point along local y of the plane of strips does not correspond to the local coordinate origin, set the final ctor argument appropriately.
Original version, allows inheritance

LocalPoint for a given MeasurementPoint
What's a MeasurementPoint?
In analogy with that used with TrapezoidalStripTopology objects, a MeasurementPoint is a 2-dim object.
The first dimension measures the angular position wrt central line of symmetry of detector, in units of strip (angular) widths (range 0 to total angle subtended by a detector).
The second dimension measures the fractional position along the strip (range -0.5 to +0.5).
BEWARE! The components are not Cartesian.

Convenience function to access azimuthal angle of extreme edge of first strip measured relative to long symmetry axis of the plane of strips.
WARNING! This angle is measured clockwise from the local y axis which means it is in the conventional azimuthal phi plane, but azimuth is of course measured from local x axis not y. The range of this angle is -(full angle)/2 to +(full angle)/2.
where (full angle) = nstrips() * angularWidth().

BEWARE: calling pitch() throws an exception.
Pitch is conventional name for width of something, but this is not sensible for a RadialStripTopology since strip widths vary with local y. Use localPitch(.) instead.

Strip in which a given LocalPoint lies. This is a float which represents the fractional strip position within the detector.
Returns zero if the LocalPoint falls at the extreme low edge of the detector or BELOW, and float(nstrips) if it falls at the extreme high edge or ABOVE.

Angle between strip and symmetry axis (=local y axis) for given strip.
This is like a phi angle but measured clockwise from y axis rather than counter clockwise from x axis. Note that 'strip' is a float with a continuous range from 0 to float(nstrips) to cover the whole detector, and the centres of strips correspond to half-integer values 0.5, 1.5, ..., nstrips-0.5 whereas values 1, 2, ... nstrips correspond to the upper phi edges of the strips.
