Bug fix (potentially silent bug), see version notes file.

Fixed some bugs with interleaved data, as well as a bug in reading timestamp data (not properties) which failed with dates prior to 1904.

Fixed a bug in which an error check I had in place was incorrectly being thrown.
Fixed parsing of object names with ' and / characters.

Also allows for only reading .tdms_index files (for debugging)

2.2 Update:
Improved speed and specificity with regard to subset handling

I was a bit quick with the last update (v2.0). It had some bugs with respect to parsing subsets of the data.

The main update to version 2 is the ability to retrieve a subset of the data from channels. In addition I've added some extra wrappers to handle data retrieval.

Ver. 1.2 - I had an incorrect minus sign when reading the timestamp property which yielded an invalid year. Data timestamp reads were correct and previously tested :)
Thanks to Ed Zechmann for pointing out the problem! Added extra conv. script v3

Fixed a major bug with reading unicode. Other small bug fixes and improvements can be seen in TDMS_VERSION_INFO.
