[#5] Review licensing and fix README to be more professional & misc
- LICENSE is now full Apache 2.0 license
- NOTICE updated to include intervening years and add YottaDB as a licensor.
- Remove curl copyright from libcurl.c; this is handled in NOTICE file.
- Add copyright to
libcurl.xc.in
file - Add full Apache copyright to
r/libcurlPluginTests.m
; previously it only had a brief copyright notice; also adjusted first line to contain the routine name; it had an old name previously which didn't match. - README has many changes
- Removed references to "I" and replaced with passive tenses
- Removed use of status variable to get the output from libcurl; it will always be zero or unvalued in case of error, so there is not need to document it.
- Examples now use full M commands in lowercase rather than single letter uppercase abbreviated commands
