Parameter `p_msft_probability` was not updated after scenario reduction.

A conditional clause was missing parentheses.

Slight performance improvement in 'inputsLoop' by avoiding looping over entire 't_' when averaging time series data.

Revenge of issue #59: Assuming no active features, so the model execution is not interrupted if no active features are declared.

Adding support for long time intervals in the first block, according to the suggestion in issue #68. Adding a couple of checks for the compatibility of the first interval block and t_jump.

Default is zero, can be changed via command line parameter --debug=[0|1|2].

Only calculate sample displacement (`ds`) for samples which have a defined starting point and which are adjacent to each other

Should fix #64

Issue #59: Model features can now only be activated through the model definition file. Commented out the features that have not bee implemented for clarity.

Implementing cyclic online states for units (inside/between samples). A new set uss(unit, s, s) added for this purpose. See issue #51.
