Reads TDMS files into Matlab.

Simplest usage is:
data = TDMS_getStruct(filename.tdms);

Advantages:
- supports reading v2 files
- doesn't require the NI DLL, thus it doesn't require 32bit windows
- supports interleaved data
- allows only reading names & properties to get a quick feel for what is in the file
- allows reading specific subsets of the data for limited memory usage

For subset retrieval examples see:

2.6

- added complex data reading support

- fixed issue where first segment didn't define objects
- lots of documentation updates
1.13.0.0

Added simple usage example to description
1.12.0.0

Just added a link to the description
1.11.0.0

Bug fix (potentially silent bug), see version notes file.
1.10.0.0

Fixed some bugs with interleaved data, as well as a bug in reading timestamp data (not properties) which failed with dates prior to 1904.
1.9.0.0

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)
1.8.0.0

2.2 Update:
Improved speed and specificity with regard to subset handling
1.7.0.0

I was a bit quick with the last update (v2.0). It had some bugs with respect to parsing subsets of the data.
1.4.0.0

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.

1.3.0.0

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
1.2.0.0

Fixed a major bug with reading unicode. Other small bug fixes and improvements can be seen in TDMS_VERSION_INFO.
1.1.0.0
