Field strength curves related issues resolved

We had identified some issues with the FCC TVFMFS code that is used for measuring field strength contours. The problems mainly existed in situations with extremely short (less than 1 km) contour distances. Apparently, this issue was known to the FCC who had replaced their TVFMFS code (which they use for their field strength curves tool) and we have made the change in our Javascript based field strength curves tool as well as in a PHP function that just recently installed to move the computation of curves off of the FCC Contour API and brought in house in order to improve response time and response reliability.
