ad64c286ff Fixed the code so that it works properly with the new row vector 
range() rather than the previous column vector range().

aa76eec386 Changed the cross_validate_trainer() function so that it catches 
invalid_svm_nu_error exceptions and just gives them a bad score rather
than letting them get out and annoy the user.

484d51039b - Added some tests for the new linspace, logspace, and cartesian_product functions. 
- Updated old tests now that range() gives row vectors instead of column vectors.
  - Fixed a bug in subm() that showed up when statically dimensioned row vectors
    were used to select a sub matrix.

  - Changed the range() function so that it returns row vectors
    instead of column vectors.

lu_decomposition::is_singular() function to avoid what appears to be a
bug in gcc 4.2.4 that caused one of the regression tests to segfault
when built with -O3.

5cc628479b - Added a bool to protect the unregister_thread_end_handler() function from 
being called from the destructor of a global object when the state object
    the unregister_thread_end_handler() function uses has already been destroyed.
  - Changed the thread pool so that it only gets destroyed if there aren't any
    outstanding threads when the program ends.  If there are threads still
    running user tasks then the thread pool never attempts to destruct.

01efae59a1 Fixed a race condition in the logger object. It was missing a needed call 
to unregister_thread_end_handler().  What could happen in some scenarios is,
during program termination, a global part of the logger object could be destructed
when it still had outstanding thread end handlers registered to it.
