CMath::qsort() - Prevent segfault when trying to sort zero-size-vectors.
Merge pull request #1144 from tklein23/master

Fixed: Segfault when sorting empty lists using CMath::qsort() (re-sent to develop)
Changed CList to CDynamicObjectArray in CCombinedDotFeatures (WIP)

Changed CList to CDynamicObjectArray in CCombinedDotFeatures
CMath::abs(complex64_t) changed to not to use std::abs()
Merge pull request #1148 from lambday/develop

CMath::abs(complex64_t) changed to not to make use of std::abs()
Added test for sorting zero-sized vectors:

- CMath::qsort(* T, ...)
- CMath::qsort(** T, ...)
- CMath::qsort_index(...)
- CMath::qsort_backward_index(...)
- CMath::parallel_qsort_index(...)

Prevented potential segfaults when sorting zero-sized vectors:

- CMath::qsort(** T)
- CMath::qsort_index(...)
- CMath::qsort_backward_index(...)
- CMath::parallel_qsort_index(...)
