Input variables

In compressed Fib objects variables are numbered and represented as natural numbers. In this, the first $n$ variables values in the Fib object are reserved for the $n$ input variables. Therefore, at this point for the variables only the number of input variables $V_E$ is interesting. For this a 64 bit natural number is stored at this location, which contains the number of input variables. After the field for the number of input variables ($V_E$) follow $V_E$ values, each, in ther order, for the default value $S_i$ of the input variable $inVar_i$. The number of bits and the encoding of the default value of $S_i$ is determined by the domain of the input variable $inVar_i$ .

The input variable field is padded with 0 bits to a full byte.
