[tauruslib-devel] [PATCH] Fix bug#243 taurustrend2D menu option fails

[cfalcon <cf...@ce...>]

The taurustrend2D setModel menu option fails. It raises a
TaurusException with 'Invalid scheme'

The widget was developed to manage just one model and
several inputs in the setModel menu option is configured.

Fix it, setting this menu option to a 'simple model'.
