Wrong parse of "-seed" and "-strain_seed" command values

[rafaelmds]

The number of parsed values for the commands -seed and -strain_seed is equal to the number of interfaces.
Hence, if specified a number of values equal to the number of layers, the last value is ignored.

To fix this issue, it is just needed to adjust the size of the arrays (used to store the strain values) to the size of layers (number of interfaces + 1).
