>[unitTest] test_ptrcast doesn't work anymore. Can't plug MatrixRotation (Eigen::Matrix4d) in dg::Matrix (Eigen::MatrixXd).
>[unitTest] matrix-homogeneous (Eigen::Transform<double,3,2>) has different constructors. matrix-homogeneous trivial constructor test out-dated now.

[eigen] Replacing jrl-mal with eigen. Removed solvers sot-h, weighted-sot, solver-hierarchical-inequalities.

>Todo: computederivation template specialization for vectorquaternion in derivator.h
>Removed solvers
>does not build

>Remove/redefine matrix tranformation classes as Eigen typedefs
>Combine all such classes in matrix-geometry.h

Add command to periodic call to recompute a signal every n iterations, where n is specified by the user. This could be useful for signals that just need to be plotted or dumped on file.

Fix bug in position control of device: control has 6 elements less than ...

Extend Device to allow for position control

 Make methods of Device virtual (second attempt)

Update travis, correct windows dependency, close #27

In windows, the deprecated flag should be placed before the
function declaration.
Also, correct macro name for dllimport.
