flexpolyline 0.1.1

• Add ORCID to author field in DESCRIPTION.
• Also limit the encoding check in the C++ binding test to 7 digits.
• Use explicit type casts instead of delta <<= 1' to avoid UBSAN runtime error ‘left shift of negative value’ in flexpolyline.h.

flexpolyline 0.1.0

First release of the flexpolyline package, which provides a binding to the C++ implementation of the flexible polyline encoding by HERE. The flexible polyline encoding is a lossy compressed representation of a list of coordinate pairs or coordinate triples. The encoding is achieved by:

1. Reducing the decimal digits of each value;
2. encoding only the offset from the previous point;
3. using variable length for each coordinate delta; and
4. using 64 URL-safe characters to display the result.

The felxible polyline encoding is a variant of the Encoded Polyline Algorithm Format by Google.
