mvsim compilation error ContainerReadOnlyProxyAccessor has no member named resize

[Logrus]

Problem

mvsim package doesn't compile via catkin_make with the following error message:

Reason

After this commit https://github.com/MRPT/mrpt/commit/12c210cefd8edf33909a590b2db8efdb1fc079a2 the interface has changed.

Proposed solution

After briefly looking over the changes in original commit I think this should fix the problem https://github.com/Logrus/mvsim/commit/ff167a02387e72c5498e99197e1e29b2001a08eb but it is worth looking over the commit, since I am not really familiar with this part.
