[Xastir-dev] first cut at geocoder

[Owen DeLong]

Presumably there is an address-range associated with the two lat-long 
values,
and, some indication of which side of the street is odd vs. even.  We should
probably do something like:

d=dist(lat/long pair)
x=delta(address pair)/2

f=d/x

a=delta(target address - base address)/2

r=fa

Then, point is a point offset to the correct side of the street from a point
along the street r distance from the base-address point towards the end
address point.

(In other words, plot the best guess of the address along the line and 
offset
to the correct side of the street).
