Title: Issue 74 asemenova

The test coverage is \+gras\+ellapx\+uncertcalc\+test\+regr\+conf\confrepo\_templates.
Unfortunately, for some systems tests fail.
They are 'test2dbad', 'advanced', 'test2dend', 'uosc8','ltisys'.
However, 'uosc8','ltisys' presumably contains disturbance.
'test2dend' looks like 'demo3secondTest', but they have
different solvability domain (the final EllTube.QArray{i}(:,:,1)).
There is a problem for 'testA0UInterval' for external point [1;1],
whose initial dot product was 1.039. The final product is 0.99987
and the point is situated almost at the boundary. If,
for example, the external point is [1;1.1] than the test passes.
Also for systems 'demo3firstTest', 'ellDemo3test' some scale
problems were found out. Ellipsoids matrices of solvability domain
for these systems have e+35 degree, thus for some inner points
the scale coefficient has e-30 degree. As a result of scale
applying an error emerges:"Tuples with indices 1 have
inconsistent values, reason: QArray is not positively defined."
However, if the initial internal point has a degree 10^17
the test passes. The next problem is with 'test2dbad'.
For some reason the external point appears
in the terminal set as a result. What is more the initial boundary point
finally belongs to the inner part of teminal part,
not the boundary. 'advanced' system looks like 'basic' system
but there is a problem with the selected external point.
