Sort and use pre-sorted character vectors in set-operations

1 2 3 | ```
sortAscii(x)
intersectPresort(pop, x)
setdiffPresort(pop, x)

`x` |
an unsorted vectors of strings |

`pop` |
a sorted vector of strings |

By default, sorting is done lexicographically in R. The routine `sortAscii`

does sorting accoring to the ASCII-order as done in C/C++.

For routines `intersectPresort`

and `setdiffPresort`

the first argument has to be sorted according to ASCII-order. This first argument is expected to be large compared to the second argument. Both functions are wrappers for optimized C++-functions performing the set-operation.

An character-vector. In case of `intersectPresort`

and `setdiffPresort`

, these vectors are unnamed.
