This function serializes data structure to string.
Important properties of s_out:
* it contains alphanumeric characters, dots, underscores, minus signs
* these symbols are grouped into words, which are separated by spaces
and Windows-style (CR+LF) newlines
* although serializer uses spaces and CR+LF as separators, you can
replace any separator character by arbitrary combination of spaces,
tabs, Windows or Unix newlines. It allows flexible reformatting of
the string in case you want to include it into text or XML file.
But you should not insert separators into the middle of the "words"
nor you should change case of letters.
* s_out can be freely moved between 32-bit and 64-bit systems, little
and big endian machines, and so on. You can serialize structure on
32-bit machine and unserialize it on 64-bit one (or vice versa), or
serialize it on SPARC and unserialize on x86. You can also
serialize it in C++ version of ALGLIB and unserialize in C# one,

KD-tree creation
This subroutine creates KD-tree from set of X-values and optional Y-values
INPUT PARAMETERS
XY - dataset, array[0..N-1,0..NX+NY-1].
one row corresponds to one point.
first NX columns contain X-values, next NY (NY may be zero)
columns may contain associated Y-values
N - number of points, N>=0.
NX - space dimension, NX>=1.
NY - number of optional Y-values, NY>=0.
NormType- norm type:
* 0 denotes infinity-norm
* 1 denotes 1-norm
* 2 denotes 2-norm (Euclidean norm)
OUTPUT PARAMETERS
KDT - KD-tree
NOTES
1. KD-tree creation have O(N*logN) complexity and O(N*(2*NX+NY)) memory
requirements.
2. Although KD-trees may be used with any combination of N and NX, they
are more efficient than brute-force search only when N >> 4^NX. So they
are most useful in low-dimensional tasks (NX=2, NX=3). NX=1 is another
inefficient case, because simple binary search (without additional
structures) is much more efficient in such tasks than KD-trees.

/*************************************************************************
Box query: all points within user-specified box.
IMPORTANT: this function can not be used in multithreaded code because it
uses internal temporary buffer of kd-tree object, which can not
be shared between multiple threads. If you want to perform
parallel requests, use function which uses external request
buffer: KDTreeTsQueryBox() ("Ts" stands for "thread-safe").
INPUT PARAMETERS
KDT - KD-tree
BoxMin - lower bounds, array[0..NX-1].
BoxMax - upper bounds, array[0..NX-1].
RESULT
number of actual neighbors found (in [0,N]).
This subroutine performs query and stores its result in the internal
structures of the KD-tree. You can use following subroutines to obtain
these results:
* KDTreeQueryResultsX() to get X-values
* KDTreeQueryResultsXY() to get X- and Y-values
* KDTreeQueryResultsTags() to get tag values
* KDTreeQueryResultsDistances() returns zeros for this request
NOTE: this particular query returns unordered results, because there is no
meaningful way of ordering points. Furthermore, no 'distance' is
associated with points - it is either INSIDE or OUTSIDE (so request
for distances will return zeros).

KDT - KD-tree

BoxMax - upper bounds, array[0..NX-1].
RESULT
number of actual neighbors found (in [0,N]).
This subroutine performs query and stores its result in the internal

obtain these results (pay attention to "ts" in their names):
* KDTreeTsQueryResultsX() to get X-values

IMPORTANT: kd-tree buffer should be used only with KD-tree object which
was used to initialize buffer. Any attempt to use biffer with
different object is dangerous - you may get integrity check
failure (exception) because sizes of internal arrays do not fit
to dimensions of KD-tree structure.
