Right now the change work on OSX, and is feature complete w/r/t the test suite.

 One file per scheduling strategy

ios::binary flag.

        I updated `make_command_test` to add every command test
        to the `tests` alias and added the missing Depends cmd.

Changed called to isnan that are ambigous to alta::isnan to avoid
compilation error problems when using clang on MacOS X.

If C++ 2011 is detected alta::isnan is equivalent to call std::isnan(x)
in other cases we simulate  isnan(x) by returning x!=x which true only when x is equal to NaN

Minor: Added CNRS Copyright as well for 2017

 Introducing more non-regression tests for Rational Fitting on 1D data that are provided as well. Furthermore, tests for asymetrical vertical segments are also added

adding more tests with UTIA. data2stats is launched as well but its output is not checked yet. To use these tests you need m100_fabric140.exr file in the build/tests/ directory

plugins.

when doing the conversion with interpolation.

[Fix] Enable loading EXR file in the UTIA plugin. I had to change the way the arguments are passed to the plugin during plugin creation.

possible due to the interface introduced by Ludo. We will have to
rollback to previous interface, or provide additional informations into
the arguments object passed.

No functional change.

This makes 'scons tests' less noisy and also allows users to preserve
the command output in .log files.

 changed the output information when loading text ALTA file in order to have coherent messages. We are loading data not fitting them

Added Tests
   + Two command line tests data2data to test more cases of conversion between MERL and ALTA and with/without filtering
   + C++ Tests using the submodule catch for the same cases
