 MUTation for INTeger representation

 This function takes the integer representation of the current
 population, mutates each element with given probability and 
 returns the resulting population.

 Syntax:  NewChrom = mutint(Chrom, VLUB, MutOpt)

 Input parameters:
    Chrom     - A matrix containing the chromosomes of the
                current population. Each row corresponds to
                an individuals string representation.
    VLUB      - Matrix containing the boundaries of each variable.
                not used here, necessary for compatibility with
                real valued mutation
    MutOpt    - (optional) Vector containing mutation options (similar
                           to real valued mutation in mutreal)
                MutOpt(1): MutRate - number containing the mutation rate -
                           probability for mutation of a variable
                           if omitted or NaN, MutRate = 1/variables per individual
                           is assumed
                MutOpt(2): MutRange - (optional) number for shrinking the
                           mutation range in the range [0 1], possibility to
                           shrink the range of the mutation depending on,
                           for instance actual generation.
                           if omitted or NaN, MutRange = 1 is assumed
                MutOpt(3): MutPreci - (optional) precision of mutation steps
                           if omitted or NaN, MutPreci = 16 is assumed

 Output parameter:
    NewChrom  - Matrix containing a mutated version of Chrom.
