php-FIT-File-Analysis

Some reasonable changes as have reorganised the directory structure, added a composer.json and began work on PHPUnit tests!

php-FIT-File-Analysis

Minor fixes/enhancements:

• Added $defn_mesgs_all as $defn_mesgs could reuse index ($local_mesg_type) and the FIT Definition would not be available for fix_data() and show_debug_info()
• Added unsigned to signed integer conversions for short integers and where not in arrays
• Timestamp fault tolerance (swim files had invalid timestamps)

php-FIT-File-Analysis

Updated the README and fixed a couple of bugs:

• Check timestamps exist before array_unique()
• Unsigned integer to signed integer conversion on 64 bit machines

Couple of fixes:

• fix_data() check that the field_name is set
• interpolate_missing_data() typo (< $max_key should have been < $min_key)

Updates and enhancements in this release:

• Support for Little and Big Endianness
• Changed creation of a couple of arrays from array() to the more modern [] way
