fixed header inclusion so that it works with new distance implementation
modified distance1 unit test to work with new distance implementation and added more test cases/combinations
rearranged code a bit; current version does not work due to the changes in the distance implementation
rearranged the split-to-segments code and made it work for all geometries
added dispatch for the LS/MLS combination
removed inclusion of geometry.hpp and added necessary includes so that the rtree can be used inside distance computations
removed my code and left only old code;
added proper preprocessor commands to include new implementation when the appropriate macro is defined
various stylistic modifications in this file; this file is not used anymore; the code used is under the same filename under the algorithms/detail/distance directory
this is the new distance implementation using R-Trees;
not all combinations have been implemented (e.g., the combination multi-point/multi-polygon);
new code is activated by means of the proper macro;
had to split the original code in two files so that it works correctly with the R-Tree code;
