phpGPX

Changed minimal PHP version to ^7.1 in composer.json. Library still should work with PHP5.5+, if you have troubles
while installing check the --ignore-platform-reqs attribute of compose.

• Added: Coordinates for remarqued statistic points (minAltitude, maxAltitude, startedAt, finishedAt) thanks to @nono303

• Fixed: Fixed VERSION string in phpGPX.php

• Feature: Real distance calculation #37 (DistanceCalculator refactor)

• Fix: Fix negative duration #58 by @neronmoon

• Fix: do SORT_BY_TIMESTAMP only for tracks with timestamps #52

• Fix: Fixed VERSION string in phpGPX.php

• Feature: Limiting maximum elevation difference to protect from spikes

• Fix: Fixed PersonParser::toXML() if there are no links provided
  Error when $person->links is null #48

I am not very proud of idea having a major release in such terrible state. This release is just freeze from 2017
compatible API and behaviour with some bugfixies. It looks like some people use the library and I want to perform some
radical refactoring. See you in 2.x.

• Fix: Fixed Copyright test

• Change: Moved PHPUnit to development dependencies.
