This method computes the mean transit time for the linear time invariant system that can be constructed from the given operator and input distribution.
It relies on the mehtod getTransitTimeDistributionDensity
using the same arguments.
object 

inputDistribution 
To compute the mean transit time for the distribution we have to compute the integral
\bar{T} = \int_0^∞ T \cdot S_r≤ft( \frac{\vec{I}}{I},0,T\right)\; dT
for the numerically computed density. To avoid issues with numerical integration we dont use ∞ as upper limit but cut off the integragion interval prematurely. For this purpose we calculate a maximum response time of the system as Lasaga
τ_{cycle} = \frac{1}{\min(λ_i)}
where λ_i are nonzero eigenvalues of the matrix {\bf A}.
