Support special case of creating PGM index for only one input element
Update piecewise_linear_model.hpp
Fix #61
Fix existing bugs:
start = 0, end = 1, we will getend - 2 == size_t(-1), which will cause heap-buffer-overflow when we callin(end - 2).start = 0, end = 1, then we havestart == end - 1. We should not calladd_point()twice for the first element.
