geometry.index example: added random test.

[SVN r84031]
geometry.index test: moved to index/test.

[SVN r84033]
geometry.index example: moved to index/example

[SVN r84034]
geometry.index test: names of test-suites names changed to the older ones in order to be consistent with the rest of Boost.Geometry.

[SVN r84036]
geometry.index: fixed numeric_limits max() calls in iterative nearest visitor.

[SVN r84037]
geometry: tabs replaced by spaces in non-extensions code.

[SVN r84038]
geometry.index test: fixed error in Jamfile related to the relocation of tests.

[SVN r84042]
geometry.index: changed exception type thrown when the allocator returns null node and doesn't throw an exception.

[SVN r84043]
geometry extensions: tabs replaced by spaces.

[SVN r84044]
geometry.index: supported environments with disabled exceptions (BOOST_NO_EXCEPTIONS)

[SVN r84045]
geometry.index test: rtree exceptions test divided into smaller ones.

[SVN r84046]
geometry.index: supported environments with disabled exceptions (BOOST_NO_EXCEPTIONS) - committed missed file.

[SVN r84047]
geometry.index: made changes required to allow copying of query iterators - geometries objects are now wrapped in predicates instead of const references, pointers to const translator instead of const references are stored in queries incremental visitors.

[SVN r84057]
geometry.index example: experimental features moved from benchmark to benchmark_experimental, added type-erased iterators to it.

[SVN r84058]
geometry.index: fixed GCC compilation error related to initialization of pointer to function wrapped in the 'satisfies' predicate.

[SVN r84059]
geometry.index: added stl container-like typedefs in rtree (reference, pointer, etc.), added type-erased iterator - currently may be enabled by define.

[SVN r84071]
geometry.index test: added test of type-erased iterators - currently may be enabled by define.

[SVN r84072]
geometry.index: fixed errors preventing copy-assigning query iterators in C++03 (caused by container::vector and Boost.Move limitation).

[SVN r84078]
geometry.index: added includes to some detail/algorithms to make possible using them without including rtree.

[SVN r84085]
geometry.index: edge values of some parameters handled more safely, changed order of rstar parameters.
