// Greasemonkey script for estate-result-page on finn.no
//
// -displays price pr sqm - uses 'real' price - see below
// -scrolls to the results - skipping stuff on top
// -hides broker names
// -hides top ad
// -hides iframe (usually ads)
// -'real' price: changes original price with the sum of original price AND fellesgjeld
// -ads orignal price to owner-info
// -calculates the average price pr sqm and displays this at the top.
//
// Norwegian:
// Endrer resultatlista til FINN Eiendom (finn.no) slik at den viser informasjon slik jeg ønsker å se den
// -viser kvadratmeterpris
// -scroller siden til der resultatet begynner
// -fjerner eiendommeglers navn
// -fjerner annonser
// -viser reell pris (dvs legger til fellesgjeld til prisen) (merker prisen der dette blir gjort)
// -viser gjennomsnittlig kvadratmeterpris for annonsene på siden 
//
// hentet fra SSB: http://www.ssb.no/vis/emner/08/02/30/bruktbolig/om.html
// Kvadratmeter pris: Kvadratmeterprisen er beregnet ved å dividere prisen på bruksarealet.
