Also:
* added missing stl header
* fixed couple of typos

For a weird reason, having all kernels in single file is causing
parse error for opencl backend on OSX platform. Splitting the
non-maximum suppression kernel into a separate file seems to fix
the issue.

The user can opt for one of the following thresholding mechanisms:
* AF_MANUAL_THRESHOLD - User has to provide two threshold ratios.
* AF_AUTO_OTSU_THRESHOLD - High threshold is chosen using otsu algorithm
  and lower threshold is computed based on lowThresholdRatio and high threshold
  value calculated using Otsu's algorithm.

detail::index is not required as the indexing is based on only
sequences.
