create a csv file with columns;
id, name, longitude, latitude, height, link, itemtype

Then use sqlite3 to 
a) update version number
b) clear out existing data
c) import csv file

~\Workspace\ShowMeHills\ShowMe\ShowMeHills\assets>sqlite3 hillsv1.db
SQLite version 3.7.12 2012-05-14 01:41:23
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> delete from mountains;
sqlite> update dbversions set ver=6;
sqlite> .mode csv
sqlite> .separator "~"
sqlite> .import planet-121017-peaks_unit_fixed.csv mountains
sqlite> .quit


if you're going to import OSM first and then want to merge in British Hills Database, you'll need
to delete the british hills from OSM to avoid duplicates. So I import OSM first, then do this;

delete from mountains where longitude between -12 and -2.960816 and latitude between 59.651034 and 61;
delete from mountains where longitude between -2.960815 and 1.367798 and latitude between 50.519248 and 61;
delete from mountains where longitude between 1.367797 and 2.098389 and latitude between 51.094323 and 61;

then import British Hills. I'm hoping those regions are ok, but it's not rigourously tested (as usual!)
