Cleaned up JSON structure that was returned
Removed all references to FF4J from the code base
Straight phase analysis now also calculates ground speed
Cleaned up testcases
Added Flight Date parsing

Hotfix: Under some circumstances igc_mapping.xml would not be included in the jar file, resulting in a crippled build that can not ever parse an IGC file.

build.gradle now refers to correct version number.
Flight summary analysis is now setting its "is complete" flag correctly.

This is the first usable, publicly available release. It performs analysis on well-formed IGC files and provides the following information back in the JSON structure:

• List of circles, each containing several things, most useful of which is the timestamp and duration
• Flight Summary structure, including the name of the pilot and the track distance over ground (circling is approximated by straight lines to avoid artificially inflating track distance).
• Indicators as to what kinds of analysis were performed
• The percentage of time spent circling
• The pilot name
• List of straight phases, each including start point, end point and distance (points contain timestamps too, so straight phases can be ordered chronologically if needed)
• List of thermals, each containing a list of circles as well as an indication of calculated wind speed and direction, if it was possible to determine this. Also contains start and end points (with timestamps etc), and total duration information.
